Nanophotonics of optical fibers

Nanophotonics, 2013
This review is concerned with nanoscale effects in highly transparent dielectric photonic structures fabricated from optical fibers. In contrast to those in plasmonics, these structures do not contain metal particles, wires, or films with nanoscale ...

Waveguide-coupled round-corner octagonal microresonator channel add-drop filters

, 2004
We report the first waveguide-coupled round-corner octagonal microresonator channel add-drop filters on silicon-nitride-on-silica substrates. By using photolithography and plasma etching, we fabricated a waveguide-coupled 50-micron sized octagonal ...

Optofluidic Sensing with Optical Microresonators

, 2018
In this thesis, detection of various fluids using optical microresonators is described. As optical microresonators, different geometries are used such as microdisks, microrings, microspheres, and microcylinders. The sensing mechanism relies on the change of optical properties, when there is a change in the amount of quantity of interest.

Microresonator and associated method for producing and controlling photonic signals with a photonic bandgap delay apparatus

, 2000
By applying a photonic signal to a microresonator that includes a photonic bandgap delay apparatus having a photonic band edge transmission resonance at the frequency of the photonic signal, the microresonator imparts a predetermined delay to the ...

Three-Dimensional Orientation of Single Molecules in a Tunable Optical λ/2 Microresonator

, 2016
A tightly focused radially polarized laser beam forms an unusual bimodal field distribution in an optical λ/2-microresonator. We use a single-molecule dipole to probe the vector properties of this field distribution by tuning the resonator length with ...
