A 1.55-æm Hybrid Integrated Wavelength-Converter Module Using Spot-Size Converter Integrated Semiconductor Optical Amplifiers on a Planar-Lightwave-Circuit Platform

A 1.55-μm hybrid integrated wavelengthconverter module was fabricated using a two-channel spot-size converter integrated semiconductor optical amplifier (SS-SOA) on a planar-lightwave-circuit (PLC) platform. Clear eye opening and penalty-free wavelength conversion were obtained at 2.5Gb/s modulation with a wide wavelength difference of 46 nm. The module showed good characteristics including low insertion loss (0.1 dB), and high conversion efficiency (−0.2 dB). It also showed stable wavelength conversion for as wide as a 13◦C temperature range. key words: hybrid integration, spot-size converter integrated
