A non-reciprocal device with multiple port inputs and outputs

The circulator is an irreversible one-way three-port component that allows light propagate in a specific direction. Circulators can be divided into nonpolarization-maintaining circulator and polarization maintaining circulator.

Non-polarization-maintaining circulator consists of birefringent beam displacer, polarization element, Faraday rotator, half-waveplate and collimator.

Polarization-maintaining optical circulator consists of input polarizer, Faraday rotator, half-waveplate, output polarizer and collimator.

CASTECH produces circulators with low insertion loss, high isolation, low polarization dependent loss and excellent temperature stability. Operating wavelength range is 450~2000nm, and connection of fiber tail can be bare fiber or FC/APC.

 

Applications:

●Fiber optical sensor system

●Bidirectional signal transmission system

●Dispersion compensation

 

Iintroduction:

CASTECH's products are produced independently throughout the entire process and can be customized according to customer needs. Refer to the following list for standard products.
