Abstract: An apparatus includes an aperture disposed through an outer layer, a folding prism adjacent to the aperture, and a multi-mode optical fiber on which the folding prism is disposed. The aperture and the folding prism are insertable into a trench disposed through a waveguide of an edge emitting integrated laser, the aperture is configured to allow a light beam that is emitted by the waveguide, through the aperture, and the folding prism is configured to redirect the allowed light beam to the multi-mode optical fiber.

Abstract: Disclosed herein are devices, methods, and systems for selectively amplifying optical signals using an optical circuit. The optical circuit includes an input port to receive a plurality of input laser signals and a switching array connected to the input port. The switching array includes a plurality of switching optical amplifiers configured to amplify a laser signal of the plurality of input laser signals as an amplified laser signal and absorb the remaining of the plurality of input laser signals. The optical circuit also includes a splitting circuit connected to the switching array. The splitting circuit is configured to split the amplified laser signal into a plurality of output laser signals.

Abstract: A light detection and ranging system that may include a light source configured to provide a second optical input signal to a second input port of a multimode interferometer that is phase shifted to a first optical input signal provided to a first input port of the multimode interferometer. The multimode interferometer is configured to provide a second optical output signal to a second optical channel coupled to a second output port of the multimode interferometer, and to provide a first optical output signal to a first optical channel coupled to a first output port of the multimode interferometer. Each of the first optical channel and the second optical channel is configured to emit light to an outside of the light detection and ranging system, and wherein the multimode interferometer is configured to generate a frequency difference between the first optical output signal and the second optical output signal.
