Introduction

Toshimitsu Matsuu is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work primarily focuses on light sources and optical coherence tomography apparatuses.

Latest Patents

Matsuu's latest patents include a light source and an optical coherence tomography apparatus that incorporates this light source. The light source features an upper electrode layer, a lower electrode layer, and an active layer situated between them. Notably, at least one of the electrode layers is divided into multiple electrodes that independently inject current into different regions of the active layer. This innovative design allows the light source to emit light by injecting current from both electrode layers into the active layer, guiding the light in the in-plane direction for output. The active layer is designed with an asymmetric multiple quantum well structure, enhancing its functionality.

Another significant patent is for a wavelength tunable surface emitting laser and an optical coherence tomography apparatus that includes this laser. This surface emitting laser consists of a lower reflector, an active layer, a gap portion, an upper reflector, and a driving unit. The unique arrangement allows for the variation of the emitted light's wavelength by adjusting the distance between the upper and lower reflectors. The driving unit is responsible for moving one of the reflectors along the optical axis of the emitted light, showcasing Matsuu's innovative approach to optical technology.
