Modeling Novel Wavelength and Ultra-Short Time Scale Phenomena in Nonlinear Optics
Abstract
Over the past two years, we significant progressed in analyzing the feedback control algorithm mathematically for a single longitudinal mode, wide aperture semiconductor laser. External delayed optical feedback introduces a large number of extraneous longitudinal modes of the extended cavity. By adjusting feedback parameters, the number of active modes in the transient evolution to the final control state could be controlled. We now have a solid understanding of how the simultaneous spatial and spectral filtering mechanism works. In particular recent works using only time delay spatially homogeneous feedback or spatially shifted feedback can be demonstrated to be of very limited utility.
