An optical isolator is an optical component which allows the transmission of light in only one direction. It is typically used to prevent unwanted feedback into an optical oscillator such as a laser cavity.

Product Introduction

An optical isolator, is an optical component which allows the transmission of light in only one direction. It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity. The operation of the device depends on the Faraday effect (which in turn is produced by magneto-optic effect), which is used in the main component, the Faraday rotator.
