The General Photonics DEP is a passive device (requiring no external power) that depolarizes laser output. The standard configuration can be used for coherence lengths less than 10 meters. Custom units can be specified for coherence lengths of multiple kilometers.
The device is packaged in a small (85 × 60 × 10 mm) aluminum box.
Applications
Minimize polarization sensitivity of fiber sensors
Depolarize pump lasers
Remove polarization sensitivity of Raman amplifiers
Eliminate polarization sensitivity of optical instruments
Eliminate the effects of PDL
Can be integrated into remote monitors
Key Features
