Flexible polymer waveguide tunable lasers
Optics Express, 2010 A flexible polymeric Bragg reflector is fabricated for the purpose of demonstrating widely tunable lasers with a compact simple structure. The external feedback of the Bragg reflected light into a superluminescent laser diode produces the lasing of a certain resonance wavelength.

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 ...

Graphene-based polymer waveguide polarizer
Optics Express, 2012 Planar-lightwave-circuit (PLC)-type graphene polarizers are fabricated by using a low loss optical polymer waveguide. The optical characteristics are investigated at a wavelength of 1.31 µm. By interface engineering with a UV-curable perfluorinated acrylate polymer resin, the graphene's electrical properties are tuned to support a transverse-magnetic ...

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 ...
