Title1: R&D in Hamamatsu Photonics and optical wavefront control device
Abstract: Hamamatsu Photonics K.K. is located in Hamamatsu city, almost center between Tokyo and Osaka in Japan, and is manufacturer of optical sensors (represented by photomultiplier tubes whose market share in the world is over 90%)), light sources, and other optical devices and their applied instruments for scientific, industrial and medical use. In this presentation, we will introduce history, products, and recent R&D in Hamamatsu, and show some hot topics including an optical wavefront controlling device (spatial light modulator : SLM) and its applications.

Title2: Research on optical semiconductor devices based on nano structure in Hamamatsu Photonics
Abstract: Optical devices used nano photonics techniques, such as plasmons, metamaterial and photonic crystal, has been developed in our research group. We have already made photonic crystal lasers practical among these devices. Progress of research on photonic crystal lasers will be described in the presentation.

Title3: Development of time-domain near-infrared spectroscopy system for medical application
Abstract: We have been developing a time-resolved diffuse optical imaging (DOI) system involving multi-channel time-resolved spectroscopy. It is highly anticipated that DOI will make it possible to capture images of breast tumors and brain activity in two or three dimensions by means of near-infrared light. The use of DOI especially for breast cancer diagnosis, so-called optical mammography, is not expected to provide precise anatomical information; however, it could provide evidence of angiogenesis, metabolic activity and oxygen consumption in the tumor.
