1. A light detection and ranging (LIDAR) system for a vehicle comprising:
a first device including a laser source and one or more optical components, the first device configured to output an optical signal associated with a local oscillator (LO) signal; and
a second device coupled to the first device, the second device including:
an optical amplifier array device including an integrated optical component and configured to amplify the optical signal, an input of the optical amplifier array device coupled to a first output of the first device through a bend in the integrated optical component for receiving the optical signal; and
a transceiver device configured to transmit the amplified optical signal to an environment and receive a returned optical signal that is reflected from an object in the environment, a first input of the transceiver device coupled to an output of the optical amplifier array device for receiving the amplified optical signal and a second input of the transceiver device coupled to a second output of the first device for receiving the LO signal.
