Abstract
Nowadays many applications require optical detection of some sorts, ranging from civil to military fields. Depending on the optical source, each sensing element needs to have distinct properties with the spectral range at the top. Choices such as sensitivity and environment play an equally important role, if not more important. The properties of the sensors can be tailored by selecting a proper material for a proper photodetector device type. The device design choice therefore will have set the performance parameters such as selectivity, sensitivity and speed. This chapter discusses such photodetection and gives requirements which need to be met. The discussion will also include the photodetection principle, device types important to this work, design considerations and relevant parameters.
