Fiber Optical Variable Splitters

The Variable Fiber Optical Splitter/Coupler splits an incoming optical signal among two output optical fibers with a continuously variable ratio controlled by an electrical input voltage from 0 to 5V. When the electrical control signal is at zero, the splitter is at a standard version of 100:0; and changes to 0:100 when the input signal is 5V.  The zero voltage ratio can be made at any pre-determined ratio with special orders.  The device also functions as coupler that combines two incoming signals into one output fiber with a variable ratio controlled by the applying voltage.  The device preserves total optical signals without loss in a 2×2 configuration.
