Innovating Integrated Photonics for
Optical Communication, Sensing, and Computing
Embedded Files
Tanemura Group focuses on integrated photonics and nanophotonics, where a large number of subwavelength structures and/or optical functional components are densely integrated on a compact semiconductor chip (a small piece of semiconductor with typically a few millimeters square). By combining these cutting-edge devices with advanced information technology, we aim to harness the strengths of both optics and electronics, fully exploiting the unique features of light, such as ultrabroad bandwidth, high spatial and spectral parallelism, and linearity, while relying on digital electronic circuits for complex control and signal processing. We target a variety of applications, including next-generation optical communication, sensing, and computing.
