Description

The magneto-optic rotation effect of a crystal, also called the Faraday effect, describes the effect of polarization rotation of an optical beam going through a layer of magneto-optic material. It plays an important role in optical experiments. This experimental system is designed to 1. observe the magneto-optic rotation effect of a material under test 2. understand the flow direction of a magnetic current vs the polarization rotation direction of a Faraday rotator 3. calculate the Verdet constant 4. demonstrate optical communication using magneto-optic modulation technique This experimental system can be used to conduct the following experiments: 1. Measure Faraday rotation angle 2. Calculate the Verdet constant of a material 3. Characterize a magneto-optic glass 4. Demonstrate optical communication using magneto-optic modulation technique
