Title:
OPTICAL MULTIPLEXER AND IMAGE PROJECTION DEVICE USING SAID OPTICAL MULTIPLEXER
Document Type and Number:
WIPO Patent Application WO/2017/065225
Kind Code:
A1
Abstract:
An optical multiplexer (10) for multiplexing a plurality of light having different wavelengths, which is provided with: a first waveguide (101) on which light having a first wavelength is incident; a second waveguide (102) on which light having a second wavelength that is shorter than the first wavelength is incident; a third waveguide (103) on which light having a third wavelength that is shorter than the second wavelength is incident; a first multiplexing part (110) which propagates light between the first waveguide (101) and the second waveguide (102); and a second multiplexing part (120) which propagates light between the first waveguide (101) and the third waveguide (103). The light having the second wavelength is propagated to the first waveguide (101) by means of the first multiplexing part (110); and the light having the third wavelength is propagated to the first waveguide (101) by means of the second multiplexing part (120).
