Model 1790

Laser Diode by EMCORE Corporation

Note: Your Quotation Request will be directed to EMCORE Corporation.

The Model 1790 from EMCORE Corporation is a Laser Diode that operates at a wavelength of 1550 nm. It provides a compact, robust solution for Frequency modulation continuous wavelength (FMCW) sensing for autonomous driving and a wide variety of other optical sensing applications. The laser delivers an optical output power of 18 dBm and has optical isolation of 50 dB. It requires an operating current of 500 mA and has a threshold current of 20 mA. The laser is DC-coupled with a built-in TEC, thermistor, and monitor photodiode. It is available in a 14-pin, OC-48 pinout compatible hermetic butterfly package with a double optical isolator mounted on the TEC making it highly immune to interference or optical frequency hopping. The laser diode is ideal for LiDAR, optical sensing, FMCW, and autonomous vehicle applications.
