The working principle of the 1x2 manually operated optical switch is based on a precise mechanical structure design. When an external manual control signal acts on the switch, it drives the internal mechanical components (such as micro motors or spring plates) to move, thereby altering the path of the optical signal. Specifically, when an input optical signal enters the switch, depending on the state of the manual control signal, the optical signal is directed to one of the two output ports, achieving switching and distribution of the optical signal.
Additionally, there is another type of 1x2 optical switch based on the Faraday effect. Its interior contains no moving components. Instead, it utilizes the principle of electromagnetic induction and the Faraday rotation effect to change the polarization state of the incident light beam. Combined with a birefringent crystal for polarization splitting, this alters the beam's propagation path, achieving the function of optical path switching.
