EMCORE Corporation, together with its subsidiaries (referred to herein as the "Company," "we," "our," or "EMCORE"), was established in 1984 as a New Jersey corporation. The Company became publicly traded in 1997 and is listed on the Nasdaq Stock Exchange under the ticker symbol EMKR. EMCORE is a leading provider of sensors for navigation in the Aerospace and Defense market as well as a manufacturer of lasers and optical subsystems for use in the cable TV industry.
EMCORE pioneered the linear fiber optic transmission technology that enabled the world's first delivery of Cable TV directly on fiber, and today is a leading provider of advanced Mixed-Signal Optics products serving the broadband communications and Aerospace and Defense markets. The Mixed-Signal Optics technology at the heart of our broadband communications products is shared with our fiber optic gyros and inertial sensors to provide the aerospace and defense markets with state-of-the-art navigations systems technology. With the acquisition of Systron Donner Inertial, Inc. ("SDI"), a navigation systems provider with a scalable, chip-based platform for higher volume gyro applications utilizing Quartz MEMS technology, in June of 2019, EMCORE further expanded its portfolio of gyros and inertial sensors with SDI's quartz MEMS gyro and accelerometer technology.
EMCORE has fully vertically-integrated manufacturing capability through our Indium Phosphide ("InP") compound semiconductor wafer fabrication facility at our headquarters in Alhambra, CA, and through our quartz processing and sensor manufacturing facility in Concord, CA. These facilities support EMCORE's vertically-integrated manufacturing strategy for quartz and fiber optic gyro products, for Navigation systems, and for our chip, laser, transmitter, and receiver products for broadband applications.
