Design of As2Se3 based chalcogenide ridge waveguide for generation of slow light
چکیده انگلیسی
A theoretical investigation of the design of a ridge waveguide in highly nonlinear As2Se3 chalcogenide glass has been carried out for the generation of stimulated Brillouin scattering (SBS) based slow light. The effective-mode-area and confinement loss of the waveguide structure has been obtained for single-mode operation and their variation with the geometrical parameters. Maximum allowable pump power and the time delay experienced by the pulse propagating in the ridge waveguide operating at a wavelength of 1.56 μm have been calculated. A maximum delay of ∼249 ns has been achieved for a 10 cm long ridge waveguide at a pump power of 390 mW. It is observed that time delay can be tuned with input pump power and length of the proposed ridge waveguide. Such tunable features of the slow light can have potential applications in realization of an all-optical network.
