Analysis of an Optical Channelization Technique for Microwave Applications
Abstract
Increasing electrical bandwidth combined with improved optical filtering allow for a new class of optical channelizers for use in radiofrequency, microwave, and millimeter-wave applications. After a brief review of existing channelization technology, an optical channelizer that uses optical local oscillators and optical filters is analyzed. Linearity and other limitations of the scheme show a strong dependence on the linearity of the optical modulator. The optical modulator is explored in both the optical domain and in the electrical domain. For the channelizer, it is shown that consideration must be given to nonlinearities in the optical field itself.
