This is an annual report on the research activities in the field of optical communications and high-speed electron devices for 1997 at the Faculty of Engineering and Reserch Center for Quantum Effect Electronics, Tokyo Institute of Techonology.

These activities are initiated by Professor Y.Suematsu(emeritus, the former president), and Prefessor S.Arai[Group_A], mainly in the field of Semiconductor Photonic Devices including Low-dimensional Quantum-well Lasers, Photonic Switching Devices, and also in the fabrication of ultra-fine structures; Professor K.Furuya and Associate Professor Y.Miyamoto[Group_B], mainly in the field of High-speed Electron Wave Devices using semiconductors, fabrication of ultra-fine structures, and OMVPE growth techniques; Associate Professor M.Asada[Group_C], mainly in the field of High-speed Electron Devices using Metal/Insulator heterostructures, and also in the theoretical investigation of the properties of Quantum-well, Quantum-wire, and Quantum-box Devices; and Associate Professor M.Watanabe[Group_D], mainly in the field of Light Emitting Devices using Semiconductor(Metal)/Insulator nano-structures and also the epitaxial growth of Metal/Insulator/Semiconductor heterostructure.

This report consists of a brief introduction of the research activities and a collection of the research papers published in 1997.
