Grating based plasmonic band gap cavities
(Optical Society of American (OSA), 2009-08)We report on a comparative study of grating based plasmonic band gap cavities. Numerically, we calculate the quality factors of the cavities based on three types of grating surfaces; uniform, biharmonic and Moiré surfaces. ... -
Laser-micromachined millimeter-wave photonic band-gap cavity structures
(American Institute of Physics, 1995)We have used laser-micromachined alumina substrates to build a three-dimensional photonic band-gap crystal. The rod-based structure has a three-dimensional full photonic band gap between 90 and 100 GHz. The high resistivity ... -
Light-controlled microwave whispering-gallery-mode quasi-optical resonators at 50W LED array illumination
(American Institute of Physics Inc., 2015)We present experimental observations of light-controlled resonance effects in microwave whispering-gallery-mode quasi-optical dielectric-semiconductor disk resonators in the frequency band of 5 GHz to 20 GHz arising due ... -
Magnetic resonance imaging assisted by wireless passive implantable fiducial e-markers
(Institute of Electrical and Electronics Engineers, 2017)This paper reports a wireless passive resonator architecture that is used as a fiducial electronic marker (e-marker) intended for internal marking purposes in magnetic resonance imaging (MRI). As a proof-of-concept ... -
Polarization characteristics of compact SOI rib waveguide racetrack resonators
(IEEE, 2005)We report on the development of compact optical racetrack resonators on silicon-on-insulator (SOI) rib waveguides. We make use of large-cross-section waveguides instead of photonic wire waveguides. We fabricated resonators ... -
RF-MEMS load sensors with enhanced Q-factor and sensitivity in a suspended architecture
(Elsevier, 2010-11-09)In this paper, we present and demonstrate RF-MEMS load sensors designed and fabricated in a suspended architecture that increases their quality-factor (Q-factor), accompanied with an increased resonance frequency shift ...
