1 Exhibit 5.1 January 14, 2000 EMCORE Corporation 394 Elizabeth Avenue Somerset, NJ 08873 Re: EMCORE Corporation Registration Statement on Form S-3 For 2,000,000 Shares of Common Stock Ladies and Gentlemen: I am Vice President and General Counsel of EMCORE Corporation, a New Jersey corporation (the "Company"). In that capacity, I have participated in the preparation of, and I am familiar with the contents of the above-referenced registration statement (the "Registration Statement"), which is concurrently being filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Act"). The Registration Statement relates to 2,000,000 shares of the Company's Common Stock (the "Shares") to be issued from time to time by the Company in one or more underwritten offerings. This opinion is being furnished in accordance with the requirements of Item 16 of Form S-3 and Item 601(b)(5)(i) of Regulation S-K. I am familiar with the corporate proceedings of the Company relating to the authorization of issuance and sale of the Shares. I have examined such certificates of public officials and certificates of officers of the Company, and the originals (or copies thereof, certified to my satisfaction) of such corporate documents and records of the Company, and such other documents, records and papers as I have deemed relevant in order to give the opinions hereinafter set forth. In this connection, I have assumed the genuineness of signatures, the authenticity of all documents submitted to me as originals and the conformity to authentic original documents of all documents submitted to me as certified, conformed, facsimile or photostatic copies. In addition, I have relied, to the extent that I deem such reliance proper, upon such certificates of public officials and officers of the Company with respect to the accuracy of material factual matters contained therein which were not independently established. I do not express or purport to express any opinions with respect to laws other than the Federal laws of the United States. As to all matters governed by the laws of the State of New Jersey involved in my opinions set forth below, I have relied, with your consent, upon an opinion of Dillon Bitar & Luther dated today and addressed to me. Based upon the foregoing, I am of the opinion that the Shares, when sold in accordance with the Plan of Distribution set forth in the Registration Statement and any amendments and prospectus supplements thereto will be validly issued, fully paid and nonassessable. I hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of my name under the caption "Legal Matters" in the Prospectus forming a part of the Registration Statement. Very truly yours, /s/ Howard W. Brodie ---------------------------------- Howard W. Brodie Vice President and General Counsel
