Description

What is a Photodiode? A photodiode is a semiconductor device with a P-N junction that converts photons (or light) into electrical current. The P layer has an abundance of holes (positive), and the N layer has an abundance of electrons (negative). Photodetection converts an optical signal into a signal of another form. Most photodetectors convert optical signals into electrical signals that can be further processed or stored. All photodetectors are square-law detectors that respond to the power or intensity, rather than the field amplitude, of an optical signal.

Applications:

• spectrometers
• light barriers
• optical data storage devices
• autocorrelators
• beam profilers
• fluorescence microscopes
• interferometers
• various types of optical sensors.
