Actuator systems for deflecting optical waveguides, and devices for processing optical signals comprising same

摘要: Actuator systems ( 10 ) are provided for inducing one or more static deflections, such as bends, in optical waveguides 12 ), to alter spectral characteristics of an signal transmitted through the waveguide. The actuator can include actuators 28 that deflect waveguide and a controller 40 controls so deflections tailored produce desired signal. be used conjunction with, example, fused fiber optic coupler form wavelength selective switch. with other types processors 14 ).
