Asynchronous GmAPD arrays offer improved blocking efficiency and frequency fidelity over conventional GmAPD arrays. This is important for array based coherent sensing. Analysis, modeling and experiments show excellent performance attainable with asyn

An optical amplifier is described using an active dielectric film. Electromagnetic scattering from this type of active film has been studied in the past using infinite plane waves. The use of unbounded fields resulted in scattering coefficients that

For partially coherent fields, where the coherence time may be quite large, a new method is described to obtain the coherence function and other statistical properties. Coherence lengths of over 100 m were measured, and it was deduced that microphoni
