PROSPECTUS SUPPLEMENT NO. 3
(to Prospectus dated September 28, 2011)

2,500,000 Shares of Common Stock
400,000 Shares of Common Stock Underlying Warrants

This Prospectus Supplement No. 3 supplements the prospectus dated September 28, 2011, as supplemented by Prospectus Supplements Nos. 1 and 2 dated January 9, 2012 and February 14, 2012, respectively (the “Prospectus”), which forms a part of our Registration Statement on Form S-1 (Registration Statement No. 333-176797) (the “Registration Statement”). This prospectus supplement is being filed to update, amend and supplement the information included or incorporated by reference in the Prospectus with the information contained and incorporated by reference in our current report on Form 8-K, filed with the Securities and Exchange Commission (the “SEC”) on February 16, 2012 (the “Current Report”). Accordingly, we have attached the Current Report to this prospectus supplement.

As disclosed in the Current Report, on February 15, 2012, we completed a 4:1 reverse stock split (the “Reverse Stock Split”) of our common stock, which became effective at 5:00 p.m., Eastern Standard Time. Upon the effectiveness of the Reverse Stock Split, every four shares of our issued and outstanding common stock were automatically combined into one issued and outstanding share of common stock. In addition, pursuant to Rule 416 under the Securities Act of 1933, as amended, the shares of our common stock that were registered under the Registration Statement were automatically proportionately reduced as a result of the Reverse Stock Split. Accordingly, the 10,000,000 shares of our common stock and the 1,600,000 shares of our common stock underlying the warrants that were originally registered under the Registration Statement have been reduced to 2,500,000 shares and 400,000 shares of our common stock respectively.

The Prospectus and this prospectus supplement relate to the resale from time to time by Commerce Court Small Cap Value Fund, Ltd., or Commerce Court, of up to 2,500,000 shares of our common stock, no par value per share, the exercise by Commerce Court of warrants, and resale from time to time by Commerce Court of 400,000 shares of common stock underlying the warrants. We are not selling any shares of common stock under the Prospectus and this prospectus supplement, and therefore, we will not receive any proceeds from the sale of shares by the selling shareholder. We will, however, receive proceeds upon the exercise of warrants to purchase an aggregate of up to 400,000 shares of our common stock held by Commerce Court to the extent such warrants are exercised for cash.

Our common stock is quoted on The NASDAQ Global Market under the symbol “EMKR”. On February 15, 2012, the last reported closing sale price of our common stock was $5.04.

This prospectus supplement should be read in conjunction with the Prospectus, which is to be delivered with this prospectus supplement. This prospectus supplement updates, amends and supplements the information included or incorporated by reference in the Prospectus. If there is any inconsistency between the information in the Prospectus and this prospectus supplement, you should rely on the information in this prospectus supplement.

Investing in our common stock involves a high degree of risk. Before making any investment in our common stock, you should read and carefully consider the risks described in the section entitled “Risk Factors” beginning on page 1 of the Prospectus, and under similar headings in any amendments or supplements to the Prospectus, including under the heading “Risk Factors” in our Annual Report on Form 10-K, filed with the SEC on December 29, 2011.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities, or determined if the Prospectus or this prospectus supplement is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus supplement is February 16, 2012.

Exhibit 99.1
Press Release
EMCORE Completes Reverse Stock Split

ALBUQUERQUE, N.M., Feb. 16, 2012 -- EMCORE Corporation (Nasdaq: EMKR) (“EMCORE”), a leading provider of compound semiconductor-based components and subsystems for the fiber optic and solar power markets, announced today the effectiveness of its 4:1 reverse stock split (the “Reverse Stock Split”) of EMCORE common stock, which became effective at 5:00 p.m., Eastern Standard Time, on February 15, 2012. EMCORE's common stock will begin trading on the NASDAQ Global Market on a split adjusted basis at the opening of trading this morning under a new CUSIP number. EMCORE's Board of Directors approved the Reverse Stock Split in January 2012, following shareholder approval of the Reverse Stock Split on June 14, 2011.

As previously disclosed, upon effectiveness of the Reverse Stock Split, every four shares of issued and outstanding EMCORE common stock were automatically combined into one issued and outstanding share of common stock without any change in the par value per share or rights and preferences of our common stock. This reduced the number of issued and outstanding shares of EMCORE common stock from approximately 94.1 million to approximately 23.5 million. The number of authorized shares of our common stock was also proportionally reduced from 200 million to 50 million. Furthermore, proportional adjustments were made to EMCORE options, warrants and other securities entitling their holders to purchase shares of EMCORE common stock.

No fractional shares were issued in connection with the Reverse Stock Split. Instead, fractional shares which resulted from the Reverse Stock Split were rounded up to the nearest whole share, other than fractional shares under EMCORE's various equity incentive plans, which fractional shares were rounded to the nearest whole share. Additional information regarding the effects of the Reverse Stock Split may be found in EMCORE's definitive proxy statement filed with the Securities and Exchange Commission on May 5, 2011.
