EMCORE introduces new LiDAR and Optical Sensing Products
EMCORE Corporation a leading provider of advanced mixed-signal products that serve the aerospace & defense and broadband communications markets, announced today the introduction of the Model 1790 1550 nm High-Power Laser Module for LiDAR (Light Detection and Ranging) and Optical Sensing. The 1790 laser module was developed for use as a CW (Continuous Wavelength) coherent optical source for next generation FMCW (Frequency Modulation Continuous Wavelength) LiDAR systems. A custom version of this product has already been adopted by a major provider of LiDAR systems for its anticipated use in autonomous vehicles.
The underlying technology for the Model 1790 has been in development for over 3 years and was designed to address demanding applications in industrial sensing and measurement. The 1790 achieves extremely narrow linewidths combined with a high-efficiency coupling scheme to enable high optical output power of 18 dBm, creating a compact, robust solution for FMCW sensing. Its monolithic design, combined with optimized coupling optics, makes it highly immune to the mode or optical frequency hopping typically found with single isolator, external cavity designs. EMCORE’s LiDAR laser technology maintains optical frequency stability over temperature, suppressing false readings caused by the mode or frequency hopping which is typical in conventional designs.
The Model 1790 laser module is DC-coupled with a built-in TEC (Thermo-Electric Cooler), thermistor and monitor photodiode. The device is packaged in a 14-pin, OC-48 pinout compatible hermetic butterfly form factor with double optical isolator mounted on the TEC. It has a wide operating temperature range from -10 °C to +65 °C and is Telcordia Technologies® GR-468 and RoHS compliant.
