1 X 8 fiber-optic switch based on an innovative waveguide converter and a micro torsion mirror

摘要

This paper reports a 1 X 8 fiber-optic switch based on an innovative waveguide converter and a micro torsion mirror. A compact 9-fiber collimator is implemented with the waveguide converter. With the micro torsion mirror aligned to the 9-fiber collimator, light from the central fiber can be steered to any of the other 8 fibers. The introduction of the waveguide converter enables a smaller and faster micro torsion mirror. The switch shows good performance, insertion loss, nonuniformity, and cross talk is <3.02 dB, <0.4 dB, and < - 35 dB respectively. Improvements of performance are expected after further optimization.
