Silicon Photonics: All-Optical Devices for Linear and Nonlinear Applications

Autor: Driscoll, Jeffrey

Silicon photonics has grown rapidly since the first Si electro-optic switch was demonstrated in 1987, and the field has never grown more quickly than it has over the past decade, fueled by milestone achievements in semiconductor processing technologi

Extrinsic Photodiodes for Integrated Mid-Infrared Silicon Photonics

Autor: Grote, Richard R., Souhan, Brian, Ophir, Noam, Driscoll, Jeffrey B., Bergman, Keren, Bakhru, Hassaram, Green, William M. J., Osgood Jr, Richard M.

Silicon photonics has recently been proposed for a diverse set of applications at mid-infrared wavelengths, the implementation of which require on-chip photodetectors. In planar geometries, dopant-based extrinsic photoconductors have long been used f

Wavelength conversion and parametric amplification of optical pulses via quasi-phase-matched FWM in long-period Bragg silicon waveguides

Autor: Lavdas, Spyros, Zhao, Shuang, Driscoll, Jeffrey B., Grote, Richard R., Osgood, Richard M., Panoiu, Nicolae C.

We present a theoretical analysis supported by comprehensive numerical simulations of quasi phase-matched four-wave mixing (FWM) of ultrashort optical pulses that propagate in weakly width-modulated silicon photonic nanowire gratings. Our study revea

Generation of parabolic similaritons in tapered silicon photonic wires: comparison of pulse dynamics at telecom and mid-IR wavelengths

Autor: Lavdas, Spyros, Driscoll, Jeffrey B., Jiang, Hongyi, Grote, Richard R., Osgood, Jr., Richard M., Panoiu, Nicolae C.

We study the generation of parabolic self-similar optical pulses in tapered Si photonic nanowires (Si-PhNWs) both at telecom (\lambda=1.55 \mu m) and mid-IR (\lambda=2.2 \mu m) wavelengths. Our computational study is based on a rigorous theoretical m
