Abstract
Approaches, apparatuses and methods for LIDAR applications based on mode-selective frequency conversion are disclosed. In one embodiment, a pulse generation unit includes a mode-locked fiber laser and optical fiber bandpass filters. In the second embodiment, a LIDAR transceiver unit based on a simple, bidirectional monostatic coaxial arrangement using off-the-shelf telecom-grade optical components includes optical fiber, fiber collimator, optical fiber circulator, optical fiber isolator and wavelength combiner. A frequency conversion detection system with single photon sensitivity includes a nonlinear optical material for frequency conversion, coupled with optimized pump pulses for efficient conversion and noise rejection, optical band pass filters for noise rejection and a single photon detection system for detecting the converted signal.
