VARIABLE OPTICAL ATTENUATOR COMPRISING HOLLOW CORE WAVEGUIDE |
摘要 |
A variable optical attenuator device is described that comprises a first optical input, a first optical output, a first optical path between the firs t optical input and the first optical output, and means for moving a shutter across said first optical path. A hollow core waveguide is provided to substantially guide light along the first optical path of the device. The device may also be used to provide an analogue beam splitting or switch function in telecommunication systems and the like.
