Summary:
Integrated-optic waveguide devices become more and more complicated to realize high functionality. Channel numbers of arrayed-waveguide gratings (AWGs) have been dramatically increased up to 400ch in single wafer. In the multi-chip configuration, 4200ch has been achieved with 5GHz channel spacing. Optical functional devices are important to solve electrical bottleneck issues. Though silica-based waveguides are simple circuit elements, various functional devices are fabricated by utilizing spatial multi-beam or temporal multi-stage interference effects such as AWGs and lattice-form programmable filters. Various kinds of optical-layer signal processing devices have been developed; they are reconfigurable optical add/drop multiplexers (ROADM), wavelength selective switches (WSS), dispersion compensators, PMD equalizers, dynamic gain equalizers, optical label recognition circuits, temporal pulse waveform shapers, and etc. Ultra-compact and CMOS compatible silicon waveguides are important for the integration of an optical component and an electronic circuit aiming at higher level of functionalities. Hybrid integration technologies with LiNbO3, InP, MEMS, and polymer will further enable us to realize much more functional and high-speed devices. This talk reviews the recent progress and future prospects of waveguide device design and its application to trunk communication systems, FTTH access networks and photonic signal processing applications.
