| Abstract: | A refractor-based 1×4 switch is developed, and its structure, principles and the factors that affect the repeatability of the device operation are described. It is independent of polarization. Adopting a single fiber-optic collimator and two dual fiber-optic collimators to couple the light paths and driving the refractor by means of a relay, the flexible switch operation can be realized. It is mainly used in optic network system connection,protection and back up. The experimental and measuring results show that the device is a small one with low loss and good reliability. |
