1690nm 10mW PM SLD Laser Diode

1690nm 10mW PM SLD Laser Diode

The 1690nm SLD is a broadband SLD operating in inherent superluminescent emission mode. Its superluminescent characteristic delivers broader spectral bandwidth under higher driving current, while conventional ASE-based SLEDs feature narrowed spectral bandwidth at elevated current. Its low coherence suppresses Rayleigh backscattering noise. Combined with high output power and wide spectral width, it counteracts optical receiver noise and improves spatial resolution for OCT and measurement sensitivity for sensing applications. This 1690 nm SLED adopts a 14-pin butterfly package and complies with Bellcore GR-468-CORE specifications.

Product features：Broad-spectrum output; polarization-maintaining fiber coupling; low coherence; high stability; intelligent control

Part Number：MP-SLD-1690-10-A81-14BF-PA

Application area：Optical Coherence Tomography | Fiber Optic Gyroscope | Fiber Sensing | Device Testing | Biological Detection
