We review our recent progress toward 100 Gbps and beyond, focusing on integrated optical devices. Topics include our
recently developed integrated optical front-ends for 100 Gbps PDM-QPSK based on multi-channel micro collimator
optics and hermetically sealed O/E converters, and PLC-LiNbO3 hybrid optical modulators for 100 Gbps PDM-QPSK.
We also describe our recent work on exceeding 100 Gbps, including 64 QAM modulators, modulation-level-selectable
modulators, and high-speed digital-analog converter ICs for future multi-level transmissions.
Opto-electronic hybrid integraiton using a silica-based planar lightwave circuit (PLC) platform is an attractive way to realize the various kinds of opto-electronic components required for future photonic networks. This paper briefly introduces the concept and basic techniques used for PLC hybrid integration, and describes recent advances in this field. We also report on several high-performance optical devices that we recently developed using this technology.
Optical hybrid integration technology has been developed using a planar lightwave circuit (PLC) platform. The platform combines a silica optical waveguide and optical active devices to realize various optical functions without restricting the type of device. We employ two additional techniques to fabricate these optical modules, namely, a multichip mounting technique for optical active devices and a PLC-PLC attachment technique. The use of a PLC platform and these techniques will make it possible to apply our technology to various optical modules from an optical transceiver module for subscriber systems to a multichannel large-scale optical module such as that employed for WDM systems.
