Optically tunable optical filter
Applied Optics, 1995We experimentally demonstrate an optically tunable optical filter that uses photorefractive barium titanate. With our filter we implement a spectrum analyzer at 632.8 nm with a resolution of 1.2 nm. We simulate a wavelength-division multiplexing system by separating two semiconductor laser diodes, at 1560 nm and 1578 nm, with the same filter.

Recent advances in the field of nonlinear optical phenomena are reviewed with particular emphasis placed on such topics as parametric oscillation, self-focusing and trapping of laser beams, and stimulated Raman, Rayleigh, and Brillouin scattering.

Optical doughnut for optical tweezers
Optics Letters, 2003We describe novel optical doughnuts for optical tweezers. With new phase functions, the proposed doughnut beams have dark cores in specified shapes. The technique can offer a simple method for creating a variety of beam shapes to match the trapped objects.

Patients with signs and symptoms consistent with acute monosymptomatic optic neuritis should undergo evaluation with gadolinium-enhanced MRI of the brain and orbits to determine whether or not they are at high risk for the development of clinically definite multiple sclerosis (CDMS).
