HEPT Lab is developing a fully solid-state, coherent 3D image sensor, the size of an Apple Airpod case, to enable autonomous devices. Our solution is resilient to harsh conditions such as bright light, dust and fog, critical for Automotive, Agtech, Robotics and Drone markets. Equally important for these markets are small size, low power and low cost. HEPT Lab’s solution combines three classes of in-house designed semiconductor devices assembled into one multi-chiplet sensor solution to achieve these requirements. A custom silicon photonic ASIC implements solid-state beam steering and coherent imaging architecture, multiple analog CMOS devices interface with the silicon photonic core and a custom InP photonic ASIC generates and conditions the laser signal.
