We have successfully demonstrated an all-in-one coherent receiver for 112-Gbit/s DP-QPSK signal detection by developing a new silica-based PLC hybrid integration technology with multi-channel micro collimator optics and hermetically sealed O/E converters.
We have developed a single-package 2ch-balanced receiver module composed of a monolithically integrated 4-PDs and a 2ch-IC. The module has excellent receiver characteristics and is suitable for 43-Gbit/s DQPSK.
Summary form only given. A high thermally resistant material for a high average power laser has been required with scalability because the present laser materials do not have the necessary thermal properties. Quartz glass is a very special material which has not only a low thermal expansion coefficient indicating high thermal tolerance, but also high transmittance in the ultraviolet region, and a...
