Fiber-based cylindrical light diffusers are often used in photo dynamic therapy to illuminate a luminal organ, such as the esophagus. The diffusers are often made of plastic and suffer from short diffusion lengths and low transmission efficiencies ov

We have generated more than 120 mW of TEM00 radiation at 467 nm by summing the resonantly enhanced output of an 845-nm GaAlAs tapered semiconductor amplifier with the intracavity field of a 1047-nm diode-pumped Nd:YLF laser, using a KTP crystal. Opti

We generated diffraction-limited laser radiation that is continuously tunable from 3.1 to 4.4 microm by mixing the output from a Ti:sapphire laser with the intracavity field of a single-frequency, 1.064-microm Nd:YAG ring laser. A peak output power o

Using fiber photosensitivity, we have made efficient, application-specific rocking filters from conventional monomode telecommunications optical fiber. Filters with a length of 10.89 m, a bandwidth of 58 nm, and a transmission of 99% at the resonant

Picosecond pulses have been generated from a cw diode-laser source using cross-phase modulation from a cw-pumped mode-locked Nd:YAG laser operating at 1.06 microm. By tuning the diode laser in the region near 1.5 microm, the effect of group-velocity

Solitons with pulse widths as short as 200 fsec have been generated through the preferential amplification of a seed signal from a continuous-wave diode laser by Raman amplification from a mode-locked Nd:YAG laser.

We analyse the penalty associated with high-order dispersion in concatenated optical filters for 40Gb/s channels in 50GHz spacing, and demonstrate a tunable high-order dispersion-compensator to mitigate this penalty. Less than 0.1dB/ROADM of penalty

We characterize the effects of neighboring channels on the accuracy of OSNR monitoring with a fractional-bit-delay Michelson interferometer. We find errors ≫ 10 dB when the center channel is flanked by higher-power constant-wave neighbors.

We report a photosensitization process in standard hydrogen loaded optical fiber. A persistent photosensitivity is produced by exposure to UV light that can be uniform or spatially tailored along the fiber length.
