Double-clad hollow core photonic crystal fiber for coherent Raman endoscope.

Performing label free coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS) in endoscope imaging is a challenge, with huge potential clinical benefit. To date, this goal has remained inaccessible because of the inherent coherent Raman noise that is generated in the fiber itself. By developing double-clad hollow core photonic crystal fiber, we demonstrate coherent an...

Predicaments in CW operation of silicon Raman lasers and amplifiers

We examine limitations of carrier removal with a p-n junction in Raman devices, namely, ineffectiveness at high optical intensities due to the applied field being screened, electrical heat dissipation, and the possibility of thermal instability. © 2006 Optical Society of America OCIS codes: (130.3120) Integrated optics devices, (190.4390) Nonlinear optics, integrated

Raman probes based on optically-poled double-clad fiber and coupler.

Two fiber Raman probes are presented, one based on an optically-poled double-clad fiber and the second based on an optically-poled double-clad fiber coupler respectively. Optical poling of the core of the fiber allows for the generation of enough 532nm light to perform Raman spectroscopy of a sample of dimethyl sulfoxide (DMSO), when illuminating the waveguide with 1064nm laser light. The Raman...
