COMPUTER-CONTROLLED VARIABLE RATIO COUPLER

$4,000.00

Computer-controlled variable-ratio coupler (CTDC) is an all-fiber construction and provides the tuning range of 0 – 100 % coupling ratio with negligible optical loss. The servo motor actuator facilitates the fine-tuning coupling ratio through the motion controller. A computer-controlled version allows user-customized operation during the experiments.

It is based on evanescent field coupling using two side polished fibers where the coupling ratio is tuned by adjusting the core-to-core geometric offset. Customer specified fibers and operating wavelengths are available including single-mode fibers, polarization maintaining fibers and other specialty fibers.
