Photon counting with photodiodes
Applied Optics, 1983Preliminary results concerning the use of silicon photodiodes designed to be used in the photon counting or Geiger mode are described. These Geiger photodiodes have higher detected quantum efficiency than photomultiplier tubes over the 5000–9000-A wavelength region and are especially superior at longer wavelengths, although they can only be used in the

LSO/photodiode and LSO avalanche photodiode detectors
IEEE Conference on Nuclear Science Symposium and Medical Imaging, 2003The performance of Lu/sub 2(1-x)/Ce/sub 2x/(SiO/sub 4/)O (LSO) detectors was assessed under laboratory conditions. The PMT (photomultiplier tube) and the APD (avalanche photodiode) gave the same energy resolution when used with LSO, although the APD displayed a thermal noise threshold of 30 keV compared to >

Applied Optics, 1975
Planar passivated germanium photodiodes have been developed whose useful response at 22 degrees C extends from 0.6 microm to 1.85 microm at a nominal operating voltage of 20 V. Typical characteristics at 22 degrees C are diode capacitance, 100 pF/cm(2); rise and fall times, 10 nsec; leakage current, 2.5 mA/cm(2) ; D*(1.54 microm) approximately 2.5 x 10(

The integrated photodiode is the first stage in the monolithically integrated optical receiver. The photodiode converts the optical power into an electrical current. The photodiode should convert photons into electron and hole pairs with maximum efficiency and to transport them to the electrodes as fast as possible.
