| dc.description | 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 . | |
