Abstract

The purpose of this paper is to present GaAs photodetectors which are suitable for Raman Spectroscopy. After a description of the devices and their technology, a complete analysis of their electrical and optical properties is presented. The results obtained are reviewed briefly in terms of static and dynamic responsivities or gains and noise figures. An example of the application of these devices in a conventionnal Raman detection system and the performances of the photodetector array in image detection are given. Furthermore, the use of the Schottky photodiode associated with an FET in Raman spectroscopic systems is discussed.
