[17p-E502-4] Optical waveguide technology for visible light and its application to laser projection

〇Toshikazu Hashimoto1 (1.NTT DTL)

Keywords:visible light, Planar Lightwave Circuit, RGB light sources

NTT has been developing "visible light PLC technology" as a "device technology that makes full use of visible laser light". In particular, RGB couplers based on the technology will make it possible to realize RGB light sources that fit into the frame of eyeglasses, and are expected to realize stress-free eyeglass-type displays when worn. These technologies will be presented in more detail in this presentation.
