Novel MEMS variable optical attenuator with expanded core waveguides

Novel MEMS variable optical attenuator with expanded core waveguides

A novel variable optical attenuator is proposed. It is composed of the planar waveguides and a comb actuator with light blocking bar. The waveguides are gradually expanded such that the single mode operation is maintained.
