Optical S Ignal Processing

چکیده
We aim to develop innovative, compact, integrated signal processors to provide cost-effective solutions for next generation ultrahigh-bandwidth networks and high performance instruments for analyzing high-speed signals and ultra-short pulses. Specifically, we aim to demonstrate three crucial component technologies: optical regenerators operating at ultra-high bit rates (greater than 40Gb/s) and for advanced data modulation formats, (such as differential phase-shift keying (DPSK)), and high capacity WDM signals; wavelength converters for application in reconfigurable optical networks and integrated optical performance monitors for both broadband signal diagnosis (including higher resolution optical sampling oscilloscopes and THz bandwidth RF spectrum analyzers) as well as dynamic provisioning and active compensation in high speed dynamic networks. The CUDOS innovation and approach is based on novel miniaturized optical signal processing devices fabricated in two dimensional planar substrates of chalcogenide (Fig. 1). These devices offer performance and footprint that will underpin signal processing solutions of future communication systems and broadband signal analyzers. The physics of these devices is based on cross phase modulation (XPM), Four Wave Mixing (FWM) and Raman scattering with dispersion engineering in strongly confined waveguides and resonant elements. Progress towards the Centre’s goals will be assisted through strong collaboration with local industry and partner universities for applying advanced photonic concepts to meet the demands of future optical communications, microwave photonics, and defence system applications.

A Monte Carlo modeling technique was used to simulate ultrasound-modulated optical tomography in inhomogeneous scattering media. The contributions from two different modulation mechanisms were included in the simulation. Results indicate that ultrasound-modulated optical signals are much more sensitive to small embedded objects than unmodulated intensity signals. The differences between embedde...
