Flexible dispersion engineering using polymer patterning in nanophotonic waveguides
Scientific Reports, 2023 We demonstrate the engineering of waveguide dispersion by lithographically patterning the polymer cladding on silicon nitride waveguide resonators. Both normal and anomalous dispersion, ranging from − 462 to 409 ps/nm/km, can be achieved for the same ...

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 ...

An Integrated Young Interferometer Based on UV-Imprinted Polymer Waveguides for Label-Free Biosensing Applications [PDF]
Journal of the European Optical Society-Rapid Publications, 2012 We demonstrate a polymer-rib waveguide Young interferometer sensor fabricated by UV imprinting. An inverted-rib waveguide structure was utilized to simplify the fabrication process. In this configuration, grooves were formed on the undercladding layer by
