摘要

An optoelectronic device that detect visible light is designed in silicon technology, peaking in 650 nm wavelength. The quadrant detector (QD) derive photocurrents by projecting a light spot on four photodiodes placed close to each other on a silicon common substrate. The photodetector is square shaped with 2.25 mm~2 per active area by each quadrant and the size of the device is 9 mm~2. This work describes a technology to develop position sensitive detectors of four quadrant optimizing geometry to increase sensitivity. We propose to integrate sensor into complementary metal-oxide-semiconductor (CMOS) technology in order to improve photodetector out signal, reducing noise generated when photodetector is so far from data acquisition system.
