Description:: Since Infrared radiation was discovered in 1800s, the research and applications on the infrared regime have been continually developed. The infrared detectors are the key technology in these applications and have been successfully used for medical imaging, light detection and ranging (LiDAR), free-space optical communication, target tracking and object identification...

Description:: In this thesis, the optical gain mechanism in low-light conditions of phototransistor detectors (PTDs) is explored. An analytical formula is derived for the physical limit on the minimum number of detectable photons for PTDs. This formulation shows that the sensitivity of the PTD, regardless of its material composition, is related...
