Abstract

This paper reports a $1\times 8$ 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 $<3.02\mathrm{dB}$, $<0.4\mathrm{dB}$, and $<-35\mathrm{dB}$ respectively. Improvements of performance are expected after further optimization.
