抄録

This paper describes a newly developed 2×2 liquid crystal optical switch for 1.3 μm single-mode fiber use. This switch state can be freely set at either the cross or the bar state. The measured performance of two prototype 2×2 liquid crystal optical switches is given. Tests confirm that the 3σ values are a maximum insertion loss of 1.5 dB, a crosstalk attenuation of more than 26.1 dB, and a return loss of more than 28.9 dB. Requirements for optical switches for fault isolation are theoretically clarified from a LAN system view point.
