| Research Abstract |
The purpose of this research was to develop semiconductor digital all-optical devices which carry out the digital processing of transmitted optical signals in photonic networks without the aid of electronic circuits, as well as to develop processing technologies for integrating them on a single semiconductor substrate monolithically, thus making one chip integrated circuits possible. More specifically, the following items were investigated.
1.Establishment of active/passive integration technology by metal-organic vapor phase epitaxy : Batch processing and integration techniques of active and passive devices have been studied by means of selective area metal-organic vapor phase epitaxy (MOVPE) ; its mechanism has been clarified, and simulation of the selective area growth has been made possible to result in the development of a computer-aided design software tool.
2.Analysis and design of semiconductor digital all-optical devices : Analysis of operation and device design have been conduct

ed on an optical logic gate based on integration of quantum-well electro-absorption(EA) optical nonlinear medium and a directional coupler, on an all-optical flip-flop by the integration of a non-linear directional coupler and a bistable laser diode, and on a high-speed all-optical flip-flop utilizing two mode switching in an active multimode interference(MMI) couper or a Mach-Zehnder interferometer(MZI).
3.Fabrication of semiconductor digital all-optical devices : Based on the design above, InGaAsP/InP digital all-optical devices operating at 1.55μm wavelength band have been fabricated, namely, the optical logic gate incorporating EA optical nonlinear medium and a directional coupler, the all-optical flip-flop integrating a nonlinear directional coupler and a bistable laser diode, the MMI bistable laser high-speed all-optical flip-flop, a digital all-optical gate switch by semiconductor optical amplifier(SOA) and MZI integration, and an integrated gain equalizer circuit with arrayed waveguide gratings.
4.Characterization of the fabricated devices : Static and dynamic all-optical operations in the fabricated devices have been characterized in detail, and then ultrafast all-optical switching, WDM gain-equalizing function, and bit-format conversion by the flip-flop have been demonstrated. Less
