Phase response characterization of semiconductor saturable absorber for applications in nonlinear optical signal processing and phase- modulated signals regeneration
The phase response of a commercial saturable absorber based on semiconductor quantum wells embedded in a resonant cavity is investigated. The nonlinear absorption change is accompanied by a variation of the spectral phase characteristic. Also, a nonlinear change in the refractive index of the material, induced by the modified carrier density, produces a weak shift in the resonant wavelength of ...
متن کاملExcitability in a semiconductor laser with saturable absorber.
We show that a monolithic and compact vertical cavity laser with intracavity saturable absorber can emit short excitable pulses. These calibrated optical pulses can be excited as a response to an input perturbation whose amplitude is above a certain threshold. Subnanosecond excitable response is promising for applications to novel all-optical devices for information processing or logical gates.
متن کاملModeling of Wavelength Conversion Using Switching Bistability in a Vertical Cavity Semiconductor Saturable Absorber
We have proposed a theoretical model to study bistable switching between two optical signals using a vertical cavity semiconductor saturable absorber (VCSSA) operating in reflection mode. The model is based on the carrier rate equation, which predicts cross-absorption phenomena within the absorber region. Simulations are carried out to investigate the effect of various cavity parameters on swit...
متن کاملSynthesis of TiO2-ZnO-ZrO2 Nanocomposites for Nonlinear Optics Applications
A sol-gel technique under ultrasonic irradiation was applied to synthesize ZrO2/TiO2/ZnOnanocomposites. X-ray diffraction analysis confirmed the successful synthesis of nanocomposites. The strain and crystalline size values of ZrO2/TiO2/ZnO nanocomposites are estimated to be 9.98×10-4 and 17.66 nm, respectively. The linear absorption coefficient of ZrO2/TiO2/ZnO nanocomposites was measure...
متن کاملNonlinear Optical Absorption of Carbon Nanostructures Synthesized by Laser Ablation of Highly Oriented Pyrolytic Graphite in Organic Solvents
In this study, Highly Oriented Pyrolytic Graphite was ablated in various polar and nonpolar solvents by Q-switched neodymium: yttrium-aluminum-garnet laser (wavelength=1064 nm, frequency=2 kHz, pulse duration=240 ns). Then, the products were examined using Scanning Electron Microscopy and UV-Vis spectroscopy. The images showed that different carbon structures such as cauliflower-like structures...
