In situ trimming of polymer optical waveguides by rapid photobleaching for tuning device specifications

Abstract

Electrooptic (EO) polymer is very attractive for ultrahigh speed optical waveguide modulators and switches because of its good speed match between the traveling microwave and optical wave. High-speed EO polymer modulators that operate at frequencies as high as 113 GHz have been demonstrated(1). Besides such advantages as high frequency response, flexible processing capability, low cost, and ease of integration with VLSI circuitry, we will demonstrate an additional advantage of EO polymer - the ability of post-fabrication device trimming.
