Segmented photodiodes are often based on silicon pin technology, with sensitivity in the visible spectral range and up to roughly 1 μm, but they are also available with other semiconductors such as indium gallium arsenide (ingaas) for detection at longer infrared wavelengths. Frequency response of a quadrant detector (s5891, hamamatsu) operating at no bias for several wavelengths with a light power of 500 w. 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.
