Publication number: 20240027869Abstract: A multi-wavelength transmitter suitable for use in LiDAR applications where an array of output beams comprising a plurality of wavelengths is spatially modulated with low amplification requirements. The optical transmitter comprises one or more light sources, such as a plurality of laser emitters operable at different wavelengths. The light source(s) are coupled, for example through one or more planar waveguides, to an optical switch network comprising one or more switches. The switch network is to route, in a time divided manner, source beams to individual ones of a plurality of switch output ports thereby modulating the wavelength of a beam exiting each of the output ports. A plurality of output couplers, for example comprising edge coupled spot size convertors, are coupled to separate ones of the switch output ports, for example through one or more planar waveguides and/or one or more beam splitters.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Applicant: Intel CorporationInventors: Jonathan Doylend, Amit Mizrahi, Faraz Monifi, Saeed Fathololoumi
