Research on InN Semiconductor Laser Diodes with High Temperature-Stability for Optical Communication Systems

Research Project Outline

To advance the information society, the development of highcapacity, cost-effective optical communications systems is desired. For this purpose, as a light source, a laser diode with temperature stability is needed. We have found that InN, a component of nitride semiconductors used in blue LEDs, emits infrared light whose wavelength is stable against temperature change. This laser has environmental advantages because it does not contain arsenic or phosphor. This project seeks to fabricate laser diodes with an InN emitting layer for optical communications systems.
