Control of optical bistability and complex dynamics of a nonlinear interferometer

Abstract

Transfer functions and dynamic characteristics of a Fabry-Perot interferometer with a multilevel resonant medium have been studied theoretically under conditions of two-frequency excitation when one of the light beams had no resonator feedback. An incoherent control method, using absorption of an independent light beam by molecules in excited energy states, has been proposed for the bistable and dynamic characteristics of a nonlinear Fabry-Perot interferometer.

Optimum diameter for laser beam and effect of temperature rise on the optical bistability hysteresis loops

“…Finally, the dependence of (n o ) upon temperature has permitted a demonstration of thermal refractive bistability in InSb at temperature using (10.6µm) wavelength radiation. In a thin material where D <<ω o the temperature rise can be estimated as follows [8,17]:…”

“…Dispersive optical nonlinearities enable all-optical functionalities including optical memories optical switches [4,5], and optical signal processors [6,7]. Renewed interest in these devices is driven by their potential to reduce system complexity and latency, for example in chip-level optical interconnects [8].…”

“…Optical bistability can be achieved in several ways, including via thermooptic effects [9], carrier injection [10], a combination of both [7,8], or via optoelectronic feedback [7,10]. Unfortunately, all these methods are inherently slow, as they implicitly or explicitly rely on carrier generation.…”

Saturation Processes in Nonlinear Media Modeled by Four-Level Configuration with Coincident Absorption and Emission Bands

“…Four--wave mixing, dynamic holograms and other nonlinear processes are interested in phase response of medium [13]. The control of nonlinear processes occurs in many works such as: control of optical bistability [4], four--wave mixing controlled by driving elds [1], and reectivity control of the dynamic PC-holograms [5]. The control of nonlinear processes occurs easily by using double--frequency optical excitation [6].…”
