Compact and lightweight 1.5 <i>μ</i>m lidar with a multi-mode fiber coupling free-running InGaAs/InP single-photon detector
We present a compact and lightweight 1.5 μm lidar using a free-running single-photon detector (SPD) based on a multi-mode fiber (MMF) coupling InGaAs/InP negative feedback avalanche diode. The ultimate light detection sensitivity of SPD highly reduces the power requirement of the laser, whilst the enhanced collection efficiency due to MMF …
