Using numerical simulations, we show that cross-gain modulation between pairs of counter-propagating pulses within a semiconductor optical amplifier can be used to detect the range and reflectivity of a target, forming a compact time-of-flight laser ranger. The range is deduced from multiple contacts along the SOA. The SOA also provides gain to the optical pulses reflected off the target. A single external component is required to provide pulses into back of the SOA, with the front of the SOA being directly coupled to the target.
