Fiber-optic complex number multiplier using an incoherent optical source

Not Accessible

Abstract

The operations achievable by means of an incoherent optical data processing system are limited to superimposition integrals involving real nonnegative impulse responses and real non-negative input data.1 The class of achievable operations can be broadened further if the results of two nonnegative operations can be subtracted. Here a demonstration of an architecture, realized by a fiber-optic system operated in the incoherent regime, capable of manipulating real non-negative quantities and complex-valued data is presented. The complex number multiplier (architecture shown in Fig. 1) is based on 2’s complement number representation in conjunction with digital multiplication by an analog convolution algorithm.2
