1. A light detection and ranging (LIDAR) device for an autonomous vehicle, the LIDAR device comprising:
a first wafer layer;
a laser assembly disposed on the first wafer layer;
a capping layer coupled to the first wafer layer and configured to seal the laser assembly;
a second wafer layer at least partially coupled to the first wafer layer; and
a photonic integrated circuit (PIC) formed on the second wafer layer, wherein the second wafer layer includes an exit feature configured to outcouple laser light from the laser assembly.
