Abstract: A LIDAR sensor system for a vehicle can include a light source configured to generate a beam; at least one optical amplifier configured to amplify the beam to produce an amplified beam; an optical power distribution network; a transmitter configured to receive the plurality of distributed beams; and one or more optics configured to emit the plurality of distributed beams. The optical power distribution network can include at least one input port configured to receive the amplified beam; one or more optical splitters configured to split the amplified beam into a plurality of distributed beams; a plurality of output ports respectively configured to provide the plurality of distributed beams; and one or more optical isolators configured to attenuate reflected signals at the plurality of output ports by coherently interfering the reflected signals.
