Phase-shifted resonance Bragg gratings in chalcogenide rib waveguides
We demonstrate the strong apodized Bragg gratings reported to date (corresponding to δn ≈ 0.01) as
well as the first phase-shifted gratings, in As2S3 chalcogenide rib waveguides using λ=532nm light and
a modified-Sagnac interferometer....
Integrated all-optical regenerator in chalcogenide glass
We report a fully integrated, passive, all-optical regenerator based in As2S3 chalcogenide glass, that exhibits a nonlinear power transfer curve with 1.9 ps optical pulses at peak in-waveguide powers below 80 W....
Integrated all-optical chalcogenide waveguide pulse regenerator: experiment and modeling
We present an integrated, all-optical, chalcogenide waveguide pulse regenerator
based on linear filtering of self phase modulated pulses. We demonstrate a nonlinear transfer
function with 1.5 ps optical pulses and find good agreement...
Ultra-strong, well-apodized Bragg gratings in chalcogenide rib waveguides
The first ultra-strong, near-perfect, raised-apodised Bragg gratings in
As2S3 chalcogenide rib waveguides using l¼532 nm light and a
modified Sagnac holographic writing setup are demonstrated. Good
agreement is achieved between...
Nonlinear pulse propagation and all-optical regeneration in chalcogenide waveguides integrated with Bragg grating filters
We report all-optical regeneration in chalcogenide glass (As2S3) waveguides integrated with Bragg gratings, demonstrating nonlinear power transfer functions with 1ps to 2ps optical pulses. We investigate several different grating structures...
Chalcogenide glasses for all-optical processing
Chalcogenide glasses, which contain S, Se or Te atoms combined with network forming elements such
as Ge, As, Sb have the largest third order optical nonlinearity of any inorganic glass. As a result they are
attractive candidates...
High performance Bragg gratings in chalcogenide glass rib waveguides written with a modified Sagnac interferometer: fabrication and characterization
We report high performance Bragg gratings in As2S3 chalcogenide glass rib waveguides, written
with a modified Sagnac interferometer for the first time. Grating growth dynamics obtained from an in-situ monitoring system are presented...
