Regarded as an extremity component for an optical communication chain, the photodetector plays a very significant role to detect and convert the optical ray penetrated by the optical fiber into an electric signal easier to exploit in the extraction of the information. Indeed, the noise of photodetection constitutes a precious phenomenon having several(More)
The knowledge of the noise levels is important for pump laser diodes as it allows to study and to locate the noise sources and their origin. 980 nm fresh and aged pump laser have been characterized by using electrical and optical noise measurements. In this work, we present the electrical and optical noises at low - mid frequency for fresh pump laser diodes(More)
This work describes the experimental and analytical studies of current noise spectral density at medium frequency in CdTe detectors. CdTe is a device of 2mm thick intrinsic II- VI semiconductor material between two metal plates of 2/spl times/20 mm/sup 2/ useful for the detection of high energy radiations. High atomic number and high stopping power are the(More)
