Abstract
An optical signal transmitter includes a laser source configured to generate light with different wavelengths, respectively; a wavelength division (WD) demultiplexer configured to redirect the light in different directions based on the different wavelengths, respectively; and a lens array including an array of lenses configured to collimate the light from the WD demultiplexer for transmission in different directions, respectively. The optical signal transmitter may be implemented in a light detection and ranging (LIDAR) apparatus. The optical signal transmitter may further include a 1×N splitter and a set of WD demultiplexers to increase the number of distinct optical signal transmissions.
