What is an optical insulator?

The optical insulator allows the beam to travel in one direction while preventing it from reflecting back in the opposite way. The device includes an input polarizer and rotator of Faraday, a crystalline piece that can rotate the plane of the polarization of the light beam when the magnetic field is applied from the outer rotator. The output polarizer reflects the polarized light at an angle of 45 degrees before the insulator leaves. The input polarizer, which passes through the beam into the insulator, allows the light to pass at the same angle that enters the Faraday effect. Such settings are common for lasers and optical communication systems. Changing the light state can be precisely controlled by a magnet. In the optical communication system, the electrical signals are first converted to light before entering the optical insulator and then are and then they are in one direction. Otherwise, part of the reflected back reflecting the lights would change the frequency of the laser, maybe it would make it ineffective, or the signals in the communication system would notThey could convey information. The data in the fiber network would be damaged and completely unreadable as soon as the receivers rework back to the electrical signals.

Optical insulator is used along with other components such as optical amplifiers, optical combinations and optical depolarizers to fully use light in the communication or measuring system. When passing through the output polarizer and then a magnetic field, each rotating the polarization plane of 45 degrees, the light reflects a total of 90 degrees. The optical diode is another term given by a device capable of directing light in this way. The effect prevents the light beam to reflect back through the fiber on the laseruporal, used as a light source, passes through the connecting lens and into the optical fiber conductor.

In addition to using lasers and optical communication systems, an optical insulator is sometimes used on the circuit for electrical insulation. Offers a protectiveWell from excessively high tension. Noise levels are also reduced, which increases more accurate measurements and optimizes data quality. The optical insulator is usually very small and can be mounted, directly on the light path, on the circuit board or a laser device based on a semiconductor.
