摘要:
The invention relates to an electro-static variable optical attenuator suitable for use in a small form factor pluggable module. A short cladding suppressing fiber, such as a double clad optical fiber, dissipates attenuated light coupled to the cladding to reduce modal interference in the output light, while also reducing PDL and WDL introduced by the off set attenuation mechanism.

The present application is directed a short distance free space optical communication link system. The system includes optical transmitter, receiver, beam expander, Rx lens and auxiliary alignment system.
摘要:
A technique for hermetically sealing an optical component in a metal package is described. Variations of the technique are described in which optical communication between the optical component and the outside environment is achieved with a ribbon fibre.
