Ortel’s 1790 laser module is characterized for use as a CW coherent optical source DFB laser operated in the 1550 nm wavelength band for LiDAR technology. Ortel’s design provides a compact, robust solution for Frequency Modulation Continuous Wavelength (FMCW) sensing for autonomous vehicles and wide variety of other optical sensing applications. The 1790 is DC-coupled with a built-in TEC, thermistor, and monitor photodiode. The device is in a 14-pin, OC-48 pinout compatible hermetic butterfly package with double optical isolator mounted on the TEC. It is highly immune to mode or optical frequency hopping typically found with single isolator, external cavity designs.
