We have investigated the Bragg gratings for surface plasmonic polaritons modes in the metal-dielectric-air waveguide and proposed a bidirectional coupler which is capable to guide the incident light at different wavelengths along two predetermined directions.
We demonstrate 268 nm period planar Bragg gratings and Mach-Zehnder interferometers fabricated by direct UV-writing. Grating reflectivities of ~30 dB and FWHM of ~0.16 nm were measured at operational wavelengths around 800 nm.
Recently developed novel psilaflat fiberpsila substrate promises flexible, long-haul integrated optical devices. Here, we present the first demonstration of one such device; an evanescent field sensor, based upon direct UV written Bragg gratings.
Integrated plasmonic devices may be isolated using plasmonic Bragg reflectors (PBRs). Systematic experimental characterization shows optimal reflection for three PBR layers, 45 nm deep. Isolation between series of nanohole array structures using PBRs is demonstrated.
Monolithic integration of 1.55-mum ring lasers with distributed Bragg reflectors (DBRs) and distributed feedback DFB lasers are presented. Such configurations show potential for mm-wave generation, wavelength tunability and are attractive for nonlinear dynamics studies in semiconductor lasers.
We observe modulational instability and pulse train generation in an integrated waveguide Bragg grating written in highly nonlinear chalcogenide glass. This Bragg soliton effect occurs at pulse energies 10,000 times lower than any previous reports.
