Optofluidics: waveguides and devices

SPIE Proceedings, 2012
In this work we review recent results of our work on optofluidics. We show that single mode optofluidic waveguides with low loss can be realized using antiresonant reflecting optical confinement (ARROW). These waveguides can be fabricated using full standard silicon technology or hybrid silicon-polymer processes.

Symmetrical Metal Cladding Waveguide for Absorption Sensing and its Sensitivity Analysis

IEEE Photonics Journal, 2017
A sensitivity analysis of absorption sensing based on the symmetrical metal-cladding waveguide is presented. The calculated reflectivity curve shows that any minute variation of the extinction coefficient due to absorption of the sample will easily give ...

Ultra-Small and Fabrication-Tolerant Silicon Polarization Beam Splitter Using Sharp Bent Directional Coupler

IEEE Photonics Journal, 2018
An ultra-small polarization beam splitter on silicon-on-insulator platform is proposed and demonstrated experimentally employing a sharp bent directional coupler. The coupling length of our device is only 0.764 μm.

Ultralow-Loss Planar $\hbox{Si}_{3}\hbox{N}_{4}$ Waveguide Polarizers

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 trifurcated waveguide problem II [PDF]

, 1994
We consider the diffraction of the dominant plane wave mode which propagates out of the end of a semi-infinite waveguide. This waveguide is made up of a half plane with a Dirichlet boundary condition and a half plane with a Neumann boundary condition ...

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 ...

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 ...

Photonic crystal and photonic wire nano-photonics based on silicon on insulator [PDF]

, 2006
Silicon-on-insulator (SOI) is a strong candidate for application in future planar waveguide integration technology, whether or not luminescence is extracted from the silicon.
