They operate by generating non-equilibrium electrical carriers upon absorbing light, which reduces the electrical resistance across two electrodes. Types of Photoconductive Detectors Alternative terms for photoconductive detectors […]

Source: MDPI Understanding Photoconductive Switches What are Photoconductive Switches? A photoconductive switch is an electrical switch that operates based on the photoconductivity of a material. This means that the material’s electrical conductance increases when exposed to light. Typically, semiconductor materials are used for these switches. When light above the material’s band gap energy is absorbed,

Source: Nature Understanding Photoconductive Sampling in Photonics Overview Photoconductive sampling is a valuable technique in optical sampling that utilizes photoconductive switches. These switches are activated by ultrashort laser pulses, enabling the temporary closure of an electrical connection. In this method, a second photoconductive switch, triggered by a delayed laser pulse, samples the signal at a
