Nanofiber-segment ring resonator

Wide FSR Triple Ring Resonator

Semiconductor nanowire ring resonator laser.

Nanowires of the wide band-gap semiconductor gallium nitride (GaN) have been shown to act as room-temperature uv lasers. Recent advances in nanomanipulation have made it possible to modify the shape of these structures from a linear to a pseudoring conformation. Changes to the optical boundary conditions of the lasing cavity affect the structure's photoluminescence, photon confinement, and lasi...

Microfabricated optofluidic ring resonator structures.

We describe the fabrication and preliminary optical characterization of rugged, Si-micromachined optofluidic ring resonator (μOFRR) structures consisting of thin-walled SiO(x) cylinders with expanded midsections designed to enhance the three-dimensional confinement of whispering gallery modes (WGMs). These μOFRR structures were grown thermally at wafer scale on the interior of Si molds defined ...

Opto-acoustical filter based on phoxonic crystal ring resonator

In this paper, a phoxonic crystal structure is designed that shows a complete phononic and photonic ban gap and is capable to guide the optical waves with transverse magnetic polarization and acoustic waves. The materials used in the structure are nylon and molybdenum, which have suitable refractive index and elastic constant. Also, it is worth of noting that the filling factor is 28% for the p...

Plasmonic Adder/Subtractor Module Based on a Ring Resonator Filter

A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...
