| The nonlinear propagation of light in alkali vapors is a well known phenomenon and has been used on multiple applications including magnetometry, slowlight, quantum applications and atomic clocks, among many others. In this thesis, the transverse optical pattern generation and nonlinearity enhancement by optical pumping in rubidium vapor are studied. Optical switches are essential components in optical networks. In such networks they are used for supplying lightpaths, protection switching and as the elements for high speed packet transmission in switched networks. In this thesis, the switching of two optical patterns, generated for a laser beam tuned at the 87 Rubidium D2 line, is used as an optical memory mechanism. Two linearly polarized beams are counter-propagated within a rubidium vapor cell in the presence of a longitudinal magnetic field. Optical patterns composed by a set of well defined points are observed in the far field. Hysteresis due to time-varying magnetic field and intensity is observed for a bistable state, composed by two well defined optical patterns. Three mechanisms are used to produce optical switching: Mechanical switching, intensity modulation of pump beam and intensity modulation of an additional beam. A rapid switching in a time below 10 microseconds is performed with a low-power additional beam of approximately 2 microwatts . | |
