1. A light detection and ranging (LIDAR) system comprising:
a seed laser configured to output a beam;
a modular modulator configured to receive the beam output from the seed laser and modulate the beam to create a modulated beam;
a modular amplifier configured to receive the modulated beam from the modular modulator and generate an amplified beam, wherein the modular amplifier comprises a particular semiconductor optical amplifier having multiple apertures; and
a modular transceiver chip coupled to the modular modulator and the modular amplifier, the modular transceiver chip configured to emit the beam perpendicularly from a first surface of the modular transceiver chip through an optical window and receive a reflected beam from a target through the optical window.
