Optical Switches
Fiber Optical Phase Switch
The NanoSpeed™ Series fiber optic phase switch is a two-port device that provides high phase-shift precision, low loss, fast response, and high optical power handling. These performance levels are achieved through a patented all-crystal design that switches between two optical paths regardless of polarization, without mechanical movement or organic materials, ensuring exceptional reliability and continuous operation. The phase shift is precisely controlled by passing or bypassing a passive waveplate, and the switch is intrinsically bidirectional—configurable for either polarization-independent or polarization-maintaining operation depending on the fiber type. Multiple switches can be cascaded and mounted on a single driver to provide a range of discrete phase-shift values.
