Hybrid polymer-titania waveguides for highly integrated circuits [PDF]
EPJ Web of Conferences, 2022 We present an innovative waveguide based on the hybridization of a titanium dioxide nano-waveguide within a polymer strip. Through simulations and design we demonstrate that the waveguide sustains principally the quasi-TM fundamental mode and that even ...

Fabrication of single-mode channel polymer waveguides using vacuum assisted microfluidic soft lithography [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 We report on the fabrication of single-mode channel waveguide structures produced by the vacuum assisted microfluidic soft lithography technique. The soft lithographic technique in conjunction with a specially designed photomask pattern and a synthesized

Nanoporous Polymer Liquid Core Waveguides [PDF]
Conference on Lasers and Electro-Optics 2010, 2010 We demonstrate liquid core waveguides defined by UV to enable selective water infiltration in nanoporous polymers, creating an effective refractive index shift Δn=0.13. The mode confinement and propagation loss in these waveguides are presented.

Enhanced Sensitivity of Silicon-Photonics-Based Ultrasound Detection via BCB Coating
IEEE Photonics Journal, 2019 Ultrasound detection via silicon waveguides relies on the ability of acoustic waves to modulate the effective refractive index of the guided modes. However, the low photo-elastic response of silicon and silica limits the sensitivity of conventional ...

Modified coupled-mode model for thermally chirped polymer Bragg gratings [PDF]
, 2010 A modified coupled-mode (CM) model is proposed for the optical behavior of thermally chirped Bragg gratings. The model accounts for the axial gradient in the modulation wavenumber, which has been ignored in the classical CM model. The model is used to

Polymer integrated waveguide optical biosensor by using spectral splitting effect
Photonic Sensors, 2017 The polymer waveguide optical biosensor based on the Mach-Zehnder interferometer (MZI) by using spectral splitting effect is investigated. The MZI based biosensor has two unequal width sensing arms. With the different mode dispersion responses of the two-
