The generated photocurrent is proportional to the power of the light received, and the conversion efficiency of the photodiode. The voltage bias on the photodiode is then increased, and the generated photocurrent becomes the gain of the amplifier. The photodiode converts optical energy to a photocurrent.
In operation, light from an optical fiber of a particular wavelength is coupled to the photodiode.
A field effect transistor acts as an amplifier, receiving the generated photocurrent from the photodiode. The avalanche photodiode is typically biased at an applied voltage sufficiently high to permit photocurrent multiplication or multiplication by impact ionization. A photocurrent is generated when the created carriers reach an electrical contact.Īn avalanche photodiode may be coupled to an optical fiber for reception and detection of optical signals. The absorbed light generates electron-hole pairs in the semiconductor material. In a conventional photodiode, incoming light of a specified wavelength is absorbed into a semiconductor, such as silicon. In general, receivers of this type use semiconductor detectors such as photodiodes and avalanche photodiodes. An optical receiver must convert optical signals received through an optical fiber into electrical signals which are accurate and free of distortion.
