Abstract
A planar optical attenuator designed as a MEMS structure has a mirror opposite an input and an output waveguide, and a TAB actuator for lateral displacement of the mirror relative to the input port and/or output port. The effective reflectivity of the mirror is variable as a function of the lateral location on the mirror. The optical attenuation is varied by varying the location on the mirror at which the optical beam is reflected.
