posted on 2023-06-09, 00:21 authored by Silvia Butera, P Vines, C H Tan, I Sandall, G S BullerTime-of-flight measurements using pulsed laser illumination in the wavelength region between 1.3 to 2.37 µm have been demonstrated with an InAs avalanche photodiode (APD). InAs is photo-sensitive at wavelengths up to 3.5 µm and with predominantly electron multipli- cation reducing detector noise, InAs APDs have clear potential for sen- sitive optical measurements of picosecond transients in the mid-wave infrared. Laboratory-based demonstrations of time-of-flight ranging using InAs APDs operated at room temperature is described.
