Broad-band optical parametric gain on a silicon photonic chip

Mark A. Foster, Amy C. Turner, Jay E. Sharping, Bradley S. Schmidt, Michal Lipson, Alexander L Gaeta
Nature
2006

Developing an optical amplifier on silicon is essential for the success of silicon-on-insulator (SOI) photonic integrated circuits. Recently, optical gain with a 1-nm bandwidth was demonstrated using… (More)

Wide bandwidth slow light using a Raman fiber amplifier.

Jay E. Sharping, Yoshitomo Okawachi, Alexander L Gaeta
Optics express
2005

We demonstrate an all-optical tunable pulse delay scheme that utilizes the power-dependent variation of the refractive index that accompanies stimulated Raman scattering in an optical fiber. Using… (More)

Resonant optical interactions with molecules confined in photonic band-gap fibers.

Physical review letters
2005

We investigate resonant nonlinear optical interactions and demonstrate induced transparency in acetylene molecules in a hollow-core photonic-band-gap fiber at 1.5 mum. The induced spectral… (More)

Optical-fiber source of polarization-entangled photons in the 1550 nm telecom band.

Optics express
2006

We present the first experimental demonstration of anomalous group-velocity dispersion (GVD) in silicon waveguides across the telecommunication bands. We show that the GVD in such waveguides can be… (More)

All-optical slow-light on a photonic chip.

Yoshitomo Okawachi, Mark A. Foster, Jay E. Sharping, Alexander L Gaeta, Qianfan Xu, Michal Lipson
Optics express
2006

We demonstrate optically tunable delays in a silicon-on-insulator planar waveguide based on slow light induced by stimulated Raman scattering (SRS). Inside an 8-mm-long nanoscale waveguide, we… (More)

All-optical, wavelength and bandwidth preserving, pulse delay based on parametric wavelength conversion and dispersion.

Optics express
2005

We demonstrate an all-optical tunable delay in fiber based on wavelength conversion, group-velocity dispersion, and wavelength reconversion. The device operates near 1550 nm and generates delays… (More)

Optical parametric oscillator based on four-wave mixing in microstructure fiber.

Jay E. Sharping, Marco Fiorentino, Prem Kumar, Robert Windeler
Optics letters
2002

We demonstrate, for the first time to our knowledge, optical parametric oscillation based on four-wave mixing in microstructure fiber. The measured wavelength-tunability range of the device (40 nm)… (More)

Generation of sub-100-fs pulses from a microstructure-fiber-based optical parametric oscillator.

Optics express
2008

We report on the generation of 70-fs pulses at a center wavelength of 880 nm using a microstructure-fiber-based optical parametric oscillator pumped by a fiber laser operating at 1032 nm. We present… (More)

Generation of correlated photons in nanoscale silicon waveguides.

Jay E. Sharping, Kim Fook Lee, +5 authors Prem Kumar
Optics express
2006

.We experimentally study the generation of correlated pairs of photons through four-wave mixing (FWM) in embedded silicon waveguides. The waveguides, which are designed to exhibit anomalous… (More)
