In-fiber devices enable a vast array of critical photonic functions ranging from signal
conditioning (amplification, dispersion control) to network management (add/drop …

Polarization dependence in microbend gratings is an inherent problem, even in perfectly
circular fibers, since antisymmetric modes are almost degenerate linear combinations of four …

We experimentally show electrically controlled guided-mode resonant thermo-optic tunable
optical filters. We design the devices using numerical methods based on rigorous coupled …

The acoustic and acoustooptic properties of a weakly multimode solid core photonic crystal
fiber (PCF) are studied. The phase velocity of the lowest order flexural acoustic mode is …

An in-line digital optical sensor was proposed. It was built from a tapered depressed-
cladding single-mode fiber and modeled as a coaxial Mach–Zehnder interferometer. The …

We propose a tunable inline mode converter based on the acousto-optic effect in optical
microwires. A theoretical model is developed to analyze the interaction between the acoustic …

The physical parameters affecting the bandwidth of acoustooptic tunable filter on single-
mode (SM) fiber are investigated. Compared to standard step-index SM fiber, we found that …
