Fiber-coupled laser diode from Ortel
1790A-063-32-FA-PM

Ortel’s (formerly Emcore) model 1790 1550 nm laser module is characterized for use as CW coherent optical source laser for LiDAR technology. Ortel’s design provides a compact, robust solution for Frequency Modulation Continuous Wavelength (FMCW) sensing for autonomous driving and wide variety of other optical sensing applications. Our lasers deliver narrow linewidth and highly efficient optical frequency modulation, combined with high optical output power of 18 dBm and unprecedented immunity from interference.

The model 1790 laser is DC-coupled with a built-in TEC, thermistor, and monitor photodiode. These devices are packaged in a 14-pin, OC-48 pinout compatible hermetic butterfly package with double optical isolator mounted on the TEC making it highly immune to mode or optical frequency hopping. Mode or optical frequency hopping causes false readings in FMCW LiDAR, whereas EMCORE’s laser technology maintains optical frequency stability over temperature suppressing false readings.
