The analytical study of optical bistability is concerned in a fullyoptimized laser Fabry-Perot system. The related phenomena ofswitching dynamics and optimization procedure are also included.From the steady state of optical bistability equation can plot theincident intensity versus the round trip phase shift (φ) for differentvalues of dark mistuning 12,6,3,1.50 , o    or finesse (F= 1, 5, 20,100). In order to obtain different optical bistable loops. The inputoutputcharacteristic for a nonlinear Fabry-Perot etalon of a differentvalues of finesse (F) and using different initial detuning (φ0) are usedin this research. When the cavity finesse values increase, the switch-ON intensity increases for the same value of (φ0), because thebistable loop width increases with increasing the cavity finessevalues.

Host Polymer

Results of measurements of optical bistability in a guest — host polymer structure are presented. A new type of polymer has been elaborated and its optical properties are described. The Fabry–Perot system has been used and the bistabile behaviour has been observed. The second order cascaded χ(2)(ω): χ(2)(2ω) process, leading to intensity dependent phase shift, has been suggested as the mechanism leading to this effect. A satisfactory model of this phenomenon was formulated.

We numerically demonstrated single-port coherent perfect loss (CPL) with a Fabry–Perot resonator in a photonic crystal (PC) nanobeam by using a perfect magnetic conductor (PMC)-like boundary. The CPL mode with even symmetry can be reduced to a single-port CPL when a PMC boundary is applied. The boundary which acts like a PMC boundary, here known as a PMC-like boundary, and can be realized by adjusting the phase shift of the reflection from the PC when the wavelength of the light is within the photonic bandgap wavelength range. We designed and optimized simple Fabry–Perot resonator and coupler in nanobeam to get the PMC-like boundary. To satisfy the loss condition in CPL, we controlled the coupling loss in the resonator by modifying the lattice constant of the PC used for coupling. By optimizing the coupling loss, we achieved zero reflection (CPL) in a single port with a PMC-like boundary.

Additional Phase

Under the “weak phase object” approximation, the component of the electron wave scattered by an object is phase shifted by π/2 with respect to the unscattered component. This phase shift has been confirmed for thin carbon films by many experiments dealing with image contrast and the contrast transfer theory. There is also an additional phase shift which is a function of the atomic number of the scattering atom. This shift is negligible for light atoms such as carbon, but becomes significant for heavy atoms as used for stains for biological specimens. The light elements are imaged as phase objects, while those atoms scattering with a larger phase shift may be imaged as amplitude objects. There is a great deal of interest in determining the complete object wave, i.e., both the phase and amplitude components of the electron wave leaving the object.
