Journal ArticleDOI
Optical rogue waves
TL;DR: This work reports the observation of rogue waves in an optical system, based on a microstructured optical fibre, near the threshold of soliton-fission supercontinuum generation—a noise-sensitive nonlinear process in which extremely broadband radiation is generated from a narrowband input.
Journal ArticleDOI
All optical switching and continuum generation in silicon waveguides
TL;DR: Results suggest that at low peak power levels the system is governed by Kerr nonlinearities, while as the input power levels increase the free carrier effects becomes dominant.
Journal ArticleDOI
Monolithic 3-D silicon photonics
TL;DR: In this article, a monolithic CMOS compatible process has been developed to realize vertically integrated devices in silicon, which involves the implantation of an oxygen into a patterned silicon substrate to form buried guiding structures.
Journal ArticleDOI
Multilayer 3-D photonics in silicon.
Prakash Koonath,Bahram Jalali +1 more
TL;DR: In this paper, a multistage optical filter with coupled microdisks on two subsurface silicon layers with bus waveguides on the surface (3rd) layer is presented.
Journal ArticleDOI
Raman amplification and lasing in SiGe waveguides.
TL;DR: The first observation of spontaneous Raman emission, stimulated amplification, and lasing in a SiGe waveguide is described and a 40 GHz frequency downshift is observed in the Raman spectrum compared to that of a silicon waveguide.
