Since the polarizer is vertically aligned, the light will be extinguished.įigure 2 shows a Faraday rotator with an input polarizer, and an output analyzer. This means the light is polarized horizontally (the direction of rotation is not sensitive to the direction of propagation). The Faraday rotator will again rotate the polarization by 45°. Light traveling in the backward direction becomes polarized at 45° by the analyzer. The analyzer then enables the light to be transmitted through the isolator. The Faraday rotator will rotate the polarization by 45°. Light traveling in the forward direction becomes polarized vertically by the input polarizer. The polarization dependent isolator, or Faraday isolator, is made of three parts, an input polarizer (polarized vertically), a Faraday rotator, and an output polarizer, called an analyzer (polarized at 45°). It is made of three parts, an input polarizer, a Faraday rotator and an analyzer. Figure 2: Faraday isolator allows the transmission of light in only one direction.
