WuhanShengshi Optical Communication Technology Co Ltd Main Business Photodetectors last for an indefinite period of time when used properly and within the specified specifications. In modern fiber-optical communications, the speed of optical transmitters and receivers is one of the most important parameters. . Typically, both the P and N regions are heavily doped due to they are utilized for Ohmic contacts.The intrinsic region in the diode is in contrast to a PN junction diode. 125 Asian Journal of Nanoscience and Materials storage. 16um*16um), thus compatible to the core of monomode fiber optical cables. Photonics and Optical Communication, Spring 2007, Dr. D. Knipp Optical Detectors 3 6. Effects of bandwidth and thermal noise of receiver on the link performance are studied in detail. The PIN diode is used in a number of areas as a result of its structure proving some properties which are of particular use. Later on, they were modified to match the requirements for cw terahertz emission[20–26].A detailed reviewon thetechnologiesand, in particular, the differences between PIN- and UTC-PDs can be found in reference [27]. Ahmad et al. First Sensor develops and manufactures photodiodes in series covering a range of technologies.

MACOM offers the highest sensitivity photodiodes for receiver applications from 2.5G up to 10G. The photodetectors which are used in these systems are : - PN junction photodiodes - PIN photodiodes - Avalanche photodiode . By reducing the surface reflectance, the performance of a PIN photodiode can be enhanced [7]. P–I–N photodiode principle of operation: To allow operation at longer wavelengths where the light penetrates more deeply into the semiconductor material, a wider depletion region is necessary. The selection of this diode can be done based on the application. In this chapter we briefly discuss the basic principle of operation of two commonly used photodiodes – namely, PIN (p-doped, intrinsic, and n-doped layers) diode and avalanche photodiodes (APD) – and study their important characteristics that are of particular relevance to optical fiber communication systems.
