Experimental Demonstration of an All-Optical NOT Logic Gate Based on Combined Brillouin Gain and Loss in an Optical Fiber
Abstract
Daisy Williams
An all-optical NOT logic gate, based on combined Brillouin gain and loss in an optical fiber, has been experimentally demonstrated. An input (IN) to the NOT gate is a probe wave, which is a combined Stokes and anti-Stokes wave, and the output (OUT) is a pump wave. The pump and probe waves undergo a combined Brillouin gain and loss interaction in an optical fiber of 20.56 km length, which enables the switching mechanism of the NOT gate. A switching contrast of 43-45% has been experimentally achieved, which is in line with previously published theoretical simulations of the NOT optical gate.
