Slot-mode-coupled optomechanical crystals.
We present a design methodology and analysis of a cavity optomechanical system in which a localized GHz frequency mechanical mode of a nanobeam resonator is evanescently coupled to a high quality factor (Q > 10(6)) optical mode of a separate nanobeam optical cavity. Using separate nanobeams provides flexibility, enabling the independent design and optimization of the optics and mechanics of the...
متن کاملSupermode dispersion and waveguide-to-slot mode transition in arrays of silicon-on-insulator waveguides.
In this Letter, we report group index measurements of the supermodes of an array of two strongly coupled silicon-on-insulator waveguides. We observe coupling-induced dispersion that is greater than the material and waveguide dispersion of the individual waveguides. We demonstrate that the system transforms from supporting the two supermodes associated with two coupled waveguides to the single m...

متن کاملParameter Study and Design of Wide-Band Widescan Dual-Polarized Tapered Slot Antenna Arrays
A parameter study of dual-polarized tapered slot antenna (TSA) arrays shows the key features that affect the wide-band and widescan performance of these arrays. The overall performance can be optimized by judiciously choosing a combination of parameters. In particular, it is found that smaller circular slot cavities terminating the bilateral slotline improve the performance near the low end of ...
متن کاملDual Band and Dual Polarized Substrate Integrated Waveguide Slot Antenna
A new dual band and dual polarized slot antenna is designed at x band, using longitudinal and transverse slots on the broad wall of the substrate integrated waveguide. The two resonances are completely apart in a low cross polarization level at both sets. antenna has a minimum radiation efficiency of 80% in both bands.
