Satellite/Microwave Communications Products - EMCORE has an established history as a pioneer of innovative RF over fiber solutions for high-performance fiber optic links in the terrestrial portion of satellite communications networks. EMCORE’s satellite/microwave band components and complete systems transport an ultra-broadband frequency range including IF, L, S, C, X, DBS, Ku, K, Ka, and Ultra-Wideband signal transport. A wide range of high-dynamic-range applications are supported including satellite antenna remoting and signal distribution, inter- and intra-facility links, site diversity systems, high-performance supertrunking links, electronic warfare systems and radar testing. EMCORE’s complete line of satellite and microwave components, subassemblies and systems eliminate the distance limitations of copper-based coaxial systems. Our rack-mount Optiva Platform RF & Microwave Fiber Optic Transport System features a wide range of SNMP (Simple Network Management Protocol) managed fiber optic transmitters, receivers, optical amplifiers, RF and optical switches, passive devices and Ethernet products that provide high-performance fiber optic transmission between satellite hub equipment and antenna dishes. EMCORE also offers a series of ruggedized microwave flange-mount transmitters, receivers and optical delay line products that meet the reliability and durability requirements of the U.S. government and defense markets. These products are tailored to the requirements of higher frequency applications such as microwave antenna signal distribution, electronic warfare systems and radar system calibration and testing. They provide our customers with high frequency, dynamic range, compact form-factors, and extreme temperature, shock and vibration tolerance. To the extent sales of our satellite/microwave communications products are related to U.S. government contracts or subcontracts, this portion of the business may be subject to renegotiation of profits or termination of contracts or subcontracts at the election of the U.S. government or an agency thereof.

Wireless Communications Products - The increasing dependence on wireless access for social media, text, email, uploading and downloading of apps, music, videos and photos has created greater demand for deployment of cost-effective, high-performance, integrated wireless Distributed Antenna System (“DAS”) networks. Wireless systems providers are building systems in subway tunnels, stadiums, hotels, high-speed trains and cruise ships. EMCORE’s has developed highly linear fiber optic products that are optimized for wireless applications which we believe integrate extremely well into these systems. They enhance bandwidth and linearity to enable the delivery of consistent, reliable signals in areas where interference is high, or signals are weak. EMCORE’s products for wireless applications include DFB lasers and optical receivers specifically designed for wireless networks, 3 GHz and 6.5 GHz fiber optic links for cellular backhaul, 4G LTE and DAS.

Chip Devices Product Line

Telecommunications companies throughout the world have been extending their Passive Optical Network (“PON”) infrastructure to business, enterprise and residential customers for several years. Since the sale of the Company’s telecom module products in 2015, EMCORE has supported this market through commercialization of products developed in our InP wafer fab to become a merchant supplier of high-performance chip devices to the Telecom industry. EMCORE’s semiconductor wafer fabrication facility features MOCVD (Metal-Organic Chemical Vapor Deposition) reactors for 2" or 3" wafer processing for InP-based devices including high-power gain chips, laser chips, Avalanche Photodiode (“APD”) and P-type Intrinsic N-type (“PIN”) photodetector chips. Our technical team has expertise in device design, epitaxial growth, wafer processing, device characterization, and Chip-On-Block (“COB”), TO-Can and Optical Sub-Assembly (“OSA”) from development through manufacturing.

Navigation Systems Product Line


EMCORE, through our vertically-integrated infrastructure, has been able to adapt the same technologies, chip designs and production assets applicable to our CATV products to the development of state-of-the-art Fiber Optic Gyroscopes (“FOG”) that have broad application within the aerospace and defense markets for land, sea, air and space navigation. This gives EMCORE the ability to leverage our high-volume infrastructure for lower volume, higher value-added product. EMCORE has expanded its FOG-based product line to include Inertial Measurement Units (“IMU or IMUs”) and Inertial Navigation Systems (“INS”) that provide superior Size, Weight and Power (“SWaP”) compared to competing or legacy systems. To the extent sales of our navigation system products are related to U.S. government contracts or subcontracts, this portion of the business may be subject to renegotiation of profits or termination of contracts or subcontracts at the election of the U.S. government or an agency thereof.

Fiber Optic Gyroscope Products - EMCORE’s FOG program has received multiple U.S. patents and has been qualified for several key military programs for applications including Unmanned Aerial Systems (“UAS”), line-of-site stabilization, aviation and aeronautics. All EMCORE FOGs feature advanced optics with only three components for simplified assembly along with Digital Signal Processing (“DSP”) for much higher accuracy, lower noise and greater efficiency. The integrated DSP also improves optical drift stability, enables higher linearity and greater environmental flexibility. EMCORE’s FOG products range from tactical to navigational grade gyros where the critical specifications for fiber length, ARW (Angle Random Walk) and drift rate improves through the product line to provide customers greater flexibility in choosing the performance level that best meets their application.

Inertial Measurement Units and Navigation Systems Products - EMCORE’s Inertial Measurement Units and Inertial Navigation Systems, based on our advanced FOG technology, provide superior SWaP compared to competing systems. Our products provide customers the flexibility to choose options from straightforward IMU operation to full navigation and are higher performance form, fit and function replacements for other IMUs and legacy systems. EMCORE’s IMUs and INS products deliver high-precision with up to five-times better performance than competing units in compact, portable form-factors that provide standalone aircraft grade navigator performance at one-third the size of competing systems. Recently EMCORE launched its new EMCORE-OrionTM series of high-precision Micro Inertial Navigation (MINAV) systems designed primarily for applications where navigation aids such as GPS are unavailable or denied. The advanced technology incorporated enables these systems to provide performance close to that of traditional RLG (Ring Laser) INS with one-third the SWaP. We believe the EMCORE MINAV’s low SWaP makes it an ideal inertial navigation system for unmanned aerial vehicle and dismounted soldier applications, and the units can operate as navigators or very precise IMUs with lower noise and greater stability than competing systems.
