Abstract

Planar punch through heterojunction phototransistors with a novel emitter control electrode and ion- implanted isolation (CE-PTHPT) are investigated. The phototransistors have a working voltage of 3-10V and high sensitivity at low input power. The base of the transistor is completely depleted under operating condition. Base current is zero. The CE-PTHPT has an increased speed and a decreased noise. The novel CE-PTHPT has been fabricated in this paper. The optical gain of GaAlAs/GaAs CE-PTHPT for the incident light power 1.3 and 43nw with the wavelength of 0.8μ+m reached 1260 and 8108. The input noise current calculated is 5.46*10^-16 A/Hz^1/2. For polysilicon emitter CE-PTHPT, the optical gain is 3083 at the input power of 0.174μ+w. The optical gain of InGaAs/InP CE-PTHPT reaches 350 for an incident power of 0.3μ+w at the wavelength of 1.55μ+m. The CE-PTHPT detectors is promising as photo detectors for optical fiber communication system.
