Optical device design with arbitrary output intensity as a function of input Voltage

We show that the designs for optical digital signal processing can be used to construct a device that gives an arbitrary function I(V), where I is the output signal intensity and V is the input voltage. This is done by applying the same voltage V to several electrodes in the system, and does not require changing the input optical frequency. This device will have applications to modulator linearization and correction for amplifier distortion. We present a numerical simulation of the device. We study the device as a function of wavelength and voltage.
