Generation of parabolic similaritons in tapered silicon photonic wires: comparison of pulse dynamics at telecom and mid-infrared wavelengths.
We study the generation of parabolic self-similar optical pulses in tapered Si photonic nanowires (Si-PhNWs) at both telecom (λ=1.55 μm) and mid-infrared (λ=2.2 μm) wavelengths. Our computational study is based on a rigorous theoretical model, which fully describes the influence of linear and nonlinear optical effects on pulse propagation in Si-PhNWs with arbitrarily varying width. Numerical si...
متن کاملRefractometric Sensor Based on Silicon Photonic Wires
Integrated optical (IO) refractometric sensors have particularly interesting applications in label-free biosensing and in measuring chemical compositions. A current trend in the research of optical refractive-index sensors focuses on making the sensors compact and highly sensitive [1-3]. We have investigated the refractometric sensing properties of grated silicon photonic wires (GSPW), fabricat...
متن کاملAntireflection and Enhanced Absorption in Tapered Silicon Photonic Crystals
Tapered silicon photonic crystals provide a broad and wide-angle antireflective window and strong optical resonances for enhanced absorption for TEand TM-polarized light, respectively, showing the potential for improving the performance of photovoltaic devices. 2010 Optical Society of America OCIS codes: (050.5298) Photonic crystals; (160.4760) Optical properties ; (220.4241) Nanostructure fab...
متن کامل50 dB parametric on-chip gain in silicon photonic wires.
A pulsed mid-infrared pump at λ=2173 nm is used to demonstrate wideband optical parametric gain in a low-loss 2 cm long silicon photonic wire. Using dispersion engineering to obtain negative second-order (β2) and positive fourth-order (β4) dispersion, we generate broadband modulation instability and parametric fluorescence extending from 1911 nm-2486 nm. Using a cw probe signal to interrogate t...
متن کاملPulse compression using a tapered microstructure optical fiber.
We calculate the pulse compression in a tapered microstructure optical fiber with four layers of holes. We show that the primary limitation on pulse compression is the loss due to mode leakage. As a fiber's diameter decreases due to the tapering, so does the air-hole diameter, and at a sufficiently small diameter the guided mode loss becomes unacceptably high. For the four-layer geometry we con...
