Abstract

A new low-loss abrupt bend structure for optical waveguide utilizes a microprism to compensate for the phase front phase difference after and before the bend corner. The compensation helps align the phase front of the eigenmode properly. Simulations indicate a 95% normalized transmitter power at 10 degrees of bend angle. A phase compensation rule and its corrections help derive the optical parameters of the prism.

2. Near-field magneto-optical microscopy using surface-plasmon waves and the transverse magneto-optical Kerr effect

Abstract

The propagation behavior of the optical near field between gold-coated tapered fiber tips and magnetic thin films is investigated. A verification that p-polarized incident light generated a strong longitudinal electric field in the fiber tip is presented from three-dimensional finite-difference time-domain calculations.
