NOEMS devices based on Slot-Waveguides
2007 Conference on Lasers and Electro-Optics (CLEO), 2007We present device applications for Nano-Opto-Electro-Mechanical System (NOEMS) structures based on the evanescent-wave bonding acting on silicon slot-waveguides. Useful all- optical or electrooptical functionalities include: phase modulation, polarization mode dispersion, near-field probing and reconfigurable optical delay.

Optical waveguides and devices
Journal of Vacuum Science and Technology, 1975A variety of practical or potential uses of low-optical-loss waveguides and devices for light modulation, deflection, and switching are reviewed. Emphasis is given to those that most likely will become necessary replacements of the bulk for systems involving signal processing, imaging radar, and optical communications.

MICROWAVE DEVICES WITH HELICALLY CORRUGATED WAVEGUIDES
2005Helical corrugation of the inner surface of an oversized circular waveguide provides very flexible dispersion characteristic of an eigenwave. Under certain corrugation parameters, the eigenwave can possess a sufficiently high and almost constant group velocity over a wide frequency band in the region of close-to-zero axial wavenumber.

Magneto-inductive waveguide devices
IEE Proceedings - Microwaves, Antennas and Propagation, 2006Devices formed from magneto-inductive waveguides based on coupled loop resonators are considered using simple analytic theory, initially assuming lossless propagation and nearest-neighbour coupling. Two-port devices that were considered include mirrors, Fabry-Perot resonators, Bragg gratings and tapers, while more general N-port devices include power ...

Polymer waveguides and device applications
Journal of Lightwave Technology, 2004We have developed highly robust polymers derived from liquid multifunctional acrylate monomers that produce waveguides that offer propagation losses equivalent to planar silica guides. This materials technology enables a variety of high performance thermo-optic devices.

SPIE Proceedings, 2009
SOI based waveguide devices are becoming more and more active. The main results of the devices investigated in our team are presented in the paper. Photonic crystal with sharp bends was made and its excess loss is 1.1±0.4dB per mirror. Two kinds of couplers, slot coupler and grating coupler, were successfully fabricated.

Novel Plasmonic Waveguides and Devices
International Photonics and Optoelectronics Meetings, 2012We present a set of simulated and fabricated devices based on hybrid plasmonic waveguides allowing for sub-wavelength light confinement. These devices increase integration level and enhance the performances of photonic integrated circuits for interconnect applications.

The general theory of transversely magnetised ferrite in rectangular waveguide is given in Chapter 6. In particular, Fig. 6.1 shows the planes where the magnetic field in the rectangular waveguide is circularly polarised in a plane parallel to the broad face of the waveguide.

Microwave plasmonic waveguides and devices
2018 IEEE International Symposium on Electromagnetic Compatibility and 2018 IEEE Asia-Pacific Symposium on Electromagnetic Compatibility (EMC/APEMC), 2018The plasmonic waveguides composed of uniform ultrathin corrugated metallic strip can support and propagate spoof surface plasmon polaritons (SSPPs) with high confinement and efficiency. However, when the surface impedance of the plasmonic waveguides are modulated periodically by using non-uniform corrugated metallic strip, then the SSPPs can be ...
