1. A method for remote imaging, comprising:
generating, by a Light Detection and Ranging (LIDAR) chip and via an output waveguide, a LIDAR output signal;
receiving, by the LIDAR chip and via a plurality of input waveguides, a plurality of LIDAR input signals respectively associated with the plurality of input waveguides, wherein a terminating facet associated with each of the plurality of input waveguides is spaced apart from another terminating facet associated with another one of the plurality of input waveguides based on a predetermined walk-off mitigating factor,
a first terminating facet of a first one of the input waveguides being positioned between 50 nm and 10 μm away from a second terminating facet of a second one of the input waveguides; and
generating, by the LIDAR chip and based on the plurality of LIDAR input signals, a plurality of electrical signals.
