May 10, 2023 Nitride Semiconductor Co., Ltd. Founder, President & CEO Yoshihiko Muramoto ◆Overview We have succeeded to develop the Photonic Crystal (hereinafter referred to as PhC) on which 100 nm size nanofabrication is performed on an ultraviolet LED (hereinafter referred to as UV-LED) with a wavelength of 385nm. We confirmed the light confinement effect of the PhC. ◆ Background A photonic crystal is a structure in which the refractive index changes periodically, and is used to confine light in a small area and enhance the interaction betwe...
