Paper Abstract

Use of the interferometric spectrum analyzer as an RF channelized receiver requires careful optimization of optical beam apodization to achieve an acceptable channel bandshape and to suppress spurious modulation produced by the self-interference of optical local oscillators which can limit dynamic range. Design techniques are shown for proper optimization and factors which limit performance in practical systems are discussed. It is shown that reference self-interference spurs can be controlled if the reference Bragg cell has a time-bandwidth product which significantly exceeds the number of channels. Other spurious suppression techniques are considered as well. Non-Gaussian apodization is shown to result in an improved bandshape for channelized receiver applications.
