A typical P-i-N photodiode is shown in Figure 4. The p-type and n-type regions are typically heavily doped because they are used for ohmic contacts. The wide intrinsic region is in contrast to an ordinary p–n diode. Photodiode Characteristics and Applications.
Silicon photodiodes are semiconductor devices responsive to high- energy particles and photons.
Noise in Photodetector Circuits.
The resistance value of the PIN diode is determined only by the forward biased dc current.
In switch and attenuator applications, the PIN diode should ideally control the RF signal level without introducing distortion . THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. Typical Photodetector Characteristics . Know various optical detectors like photodiodes , p-i-n diodes and avalanche diodes. Define figures of merit of the detectors. Know about different sources of noise in detectors and the significance of signal to noise ratio.
Table 1: Response time and gain of different photodetectors. Physics of semiconductor devices - S. PSD (position sensitive detector). It is sensitive to visible and near infrared radiation.
Si photodiodes provide the following features and are widely used to detect the . High sensitivity in visible to near infrared range. Katholieke Universiteit Leuven (Belgium). The analysis and optimization of photodetectors and their topologies are essential in optical communications. A photodetector is mainly characterized by its bandwidth, quantum yield and noise.
The HPI-23G and HPI-6FFRare ideal as detectors. Adobe Reader is available from Adobe Systems . Optical Fibres and Telecommunications - Introduction. This photodiode is suitable for FSO(free space optics) and high-speed pulsed . The flat glass used as the light input window is less susceptible to scratches than resin windows, allowing easy handling. Si PIN photodiode for optical power meters. COB type, applicable to lead-free solder reflow.
