Organization, Consolidation and Presentation of Financial Statements [Abstract]
1. Description of Business	Business Overview
	Applied Optoelectronics, Inc., or AOI, was originally incorporated in Texas in February of 1997 and then converted to a Delaware corporation in March of 2013. AOI together with its wholly-owned subsidiaries are collectively referred to as the Company. The Company is a leading, vertically integrated provider of fiber-optic networking products, primarily for three networking end-markets: cable television, fiber-to-the-home and internet data centers. The Company designs and manufactures a wide range of optical communications products at varying levels of integration, from components, subassemblies and modules to complete turn-key equipment.
	The Company has manufacturing and research and development facilities in all three of its locations, located in the U.S., Taiwan and China. At its corporate headquarters and manufacturing facilities in Sugar Land, Texas, the Company primarily manufactures lasers and laser components and performs research and development activities for laser component products. The Company operates a division in Taipei, Taiwan that primarily manufactures transceivers for both the data center and fiber-to-the-home (“FTTH”) markets and performs research and development activities for the transceiver products. The Company operates in Ningbo, China through its wholly-owned subsidiary Prime World International Holdings, Ltd. (incorporated in the British Virgin Islands), the sole parent of Global Technology, Inc. (incorporated in the People’s Republic of China). Through Global Technology, the Company primarily manufactures Cable TV Broadband (“CATV”) systems and equipment and performs research and development activities for the CATV products.
	Interim Financial Statements
	The condensed consolidated financial statements of the Company, as of March 31, 2015 and December 31, 2014 and for the three months ended March 31, 2015 and March 31, 2014, have been prepared in accordance with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, the Company has omitted certain information and notes normally provided in the Company’s annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. generally accepted accounting principles (“GAAP”). These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2014. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results expected for the entire fiscal year. All significant intercompany accounts and transactions have been eliminated.
	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, allowance for doubtful accounts, valuation allowances for deferred tax assets, inventory reserve, share-based compensation expense, estimated useful lives of property and equipment, and taxes.

Accounting Policies [Abstract]
2. Significant Accounting Policies	There have been no changes in the Company’s significant accounting policies for the three months ended March 31, 2015, as compared to the significant accounting policies described in its Annual Report.
	Recent accounting pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer, as opposed to recognizing revenue when the risks and rewards transfer to the customer under the existing revenue guidance. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016. Early adoption is not permitted. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company is in the process of evaluating the impact of adoption on its consolidated financial statements.

4_Earnings_Per_Share

4. Earnings Per Share	3 Months Ended
	Mar. 31, 2015
Net income (loss) per share
4. Earnings Per Share	Basic net income (loss) per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from stock options, restricted stock units/awards and warrants outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive, and therefore for those periods basic and dilutive earnings per share are the same.
	The following table sets forth the computation of the basic and diluted net loss per share for the periods indicated (in thousands, except per share amounts):
		Three months ended March 31,
		2015			2014
	Numerator:
	Net income (loss)	$	(675	)	$	85

	Basic	$	(0.05	)	$	0.01
	Diluted	$	(0.05	)	$	0.01
	The following potentially dilutive securities were excluded from the computation of diluted net income (loss) per share as their effect would have been anti-dilutive (in thousands):
		Three months ended March 31,
		2015			2014
	Employee stock options		412			–

Interim Financial Statements	Interim Financial Statements
	The condensed consolidated financial statements of the Company, as of March 31, 2015 and December 31, 2014 and for the three months ended March 31, 2015 and March 31, 2014, have been prepared in accordance with the instructions on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). In accordance with those rules and regulations, the Company has omitted certain information and notes normally provided in the Company’s annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. generally accepted accounting principles (“GAAP”). These condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K (“Annual Report”) for the fiscal year ended December 31, 2014. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results expected for the entire fiscal year. All significant intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates
	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, allowance for doubtful accounts, valuation allowances for deferred tax assets, inventory reserve, share-based compensation expense, estimated useful lives of property and equipment, and taxes.
Recent accounting pronouncements	Recent accounting pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). The standard provides companies with a single model for use in accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific revenue guidance. The core principle of the model is to recognize revenue when control of the goods or services transfers to the customer, as opposed to recognizing revenue when the risks and rewards transfer to the customer under the existing revenue guidance. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016. Early adoption is not permitted. The guidance permits companies to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. The Company is in the process of evaluating the impact of adoption on its consolidated financial statements.
