Ultralow-Loss Planar
IEEE Photonics Journal, 2013 We demonstrate broadband (1500-1620 nm) and low-loss planar waveguide polarizers with measurement-limited on-chip extinction as high as 75 dB. Polarizers can be fabricated in higher confinement 100-nm-thick as well as lower confinement 40-nm-thick Si3N4 ...

A Waveguide Polarization Toolset Design Based on Mode Beating
IEEE Photonics Journal, 2011 A toolset of waveguide elements is examined, which can be combined to produce polarization functional devices in a single contiguous waveguide. In particular, waveguide implementations of an optical isolator and a polarization modulator are discussed ...

Optical fibre taper-enabled waveguide photoactuators
Nature Communications, 2022 Despite promising devices, waveguide photoactuators actuating performances have been fundamentally restricted by the nature of standard optical fibres. To overcome these challenges, authors propose an optical fibre taper-enabled waveguide photoactuator ...

NONLINEAR EFFECTS IN WAVEGUIDE DEVICES
Le Journal de Physique Colloques, 1988 All-optical switching and routing of light in fibers and waveguides has the potential of handling optical signals at ul rahigh speed. By using very rapid electronic nonlinearities in transparent materials, extremely fast switching free of thermal problems could be obtained. The guided wave environment reduces the peak power requirements.

Two-Mode Waveguide Characterization by Intensity Measurements from Exit Face Images
IEEE Photonics Journal, 2012 A method that characterizes two-mode waveguides whose modes cannot be selectively excited (such as buried waveguides) is presented and demonstrated. The theoretical results are presented for $N$ modes, although for the sake of simplicity, only the two ...

Plasmonic coaxial waveguide-cavity devices
Optics Express, 2015 We theoretically investigate three-dimensional plasmonic waveguide-cavity structures, built by side-coupling stub resonators that consist of plasmonic coaxial waveguides of finite length, to a plasmonic coaxial waveguide. The resonators are terminated either in a short or an open circuit.
