New type of polarization-independent single chip 6-gate integrated PLZT optical switch with single-mode fiber pigtails

摘要

Abstract: A new type of polarization-independent single chip 6-gate integrated PLZT optical switch with single-mode fiber pigtails is reported. The switch consists of converging-and-compressing type of polarization-independent 1 $MUL 1 PLZT optical switch as the elementary gates. The switch has a working voltage of 175 V, an extinction ratio of $GRT 34 dB, an insertion loss of $LS 6 dB, and a 3 dB bandwidth of $LS 600 nm when operating at 1.3 - 1.5 $mu@m waveband, as well as an on/off response time of sub-$mu@s.!10
