Abstract
We measured the characteristics of a quadrant-type avalanche photodiode (APD). Its transition region between the adjacent cells had a narrow width of 35 ?m. As the multiplication factor of the quadrant APD was limited by the variety of that among the quadrant cells, the maximum multiplication factor was about 30. We investigated the performance on applying the quadrant APD to a laser tracking system. A noise- equivalent angle of less than 1 ?rad (rms) was achieved at a received optical power of more than 4 pW. The quadrant APD compared favorably with a photodiode quadrant detector when the received power was less than 100 pW.
