Paper Abstract

Position sensitive detectors (PSD) use the lateral photo effect to determine the centroid position of an incident light spot focused on it. A 65-pin ceramic packaged 4×4 arrayed position sensitive detector was fabricated first time as a new prototype of Hartmann-Shack wavefront sensor. The detector, consisting of 16 tetra-lateral sensitive areas, is a p-n-n+ configuration made on 3-inch <111> n-type high resistance crystal silicon substrate. A 100nm antireflection SiO2 thin film was formed on the surface and a multi-layer cover glass with transmissivity > 98% from 400nm to 950nm. The main parameters of the arrayed as wavefront detector, such as reverse voltage, dark current photosensitivity, response time were reported in the paper.
