We propose and numerically investigate mid-infrared supercontinuum generation in dispersion-engineered Al<inf>0.18</inf>Ga<inf>0.82</inf>As-based strip waveguides. An ultra-board supercontinuum ranging from 2 to 15.9 µm is obtained when pump pulses with center wavelength of 4.1 µm and peak power of 3.35 kW are used.
High performance all-optical quantizer based on silicon waveguide is believed to have significant applications in photonic integratable optical communication links, optical interconnection networks, and real-time signal processing systems. In this paper, we propose an integratable all-optical quantizer for on-chip and low power consumption all-optical… (More)
All-optical analog-to-digital converters based on the third-order nonlinear effects in silicon waveguide are a promising candidate to overcome the limitation of electronic devices and are suitable for photonic integration. In this paper, a 2-bit optical spectral quantization scheme for on-chip all-optical analog-to-digital conversion is proposed. The… (More)
