In classical guitar acoustic spectra, the lowest frequency body mode's amplitude often
significantly surpasses that of the string overtones. However, the characteristics of the body …

We report that the birefringence of the polarization convertor in silicon-on-Insulator channel
waveguide could be enlarged using photonic crystals. The photonic crystals consist of …

Introducing defects in photonic crystals is a common method for manipulating and
controlling electromagnetic wave transmission. By introducing defects in photonic crystal …

In this work, we shed light on a theoretical study of photonic crystal (PhC) cavities on Gallium
Nitride (GaN). Particularly, the photonic band gap (PBG), resonant wavelength and quality …

An ultrahigh-Q hybrid cavity using a graded multiheterostructure and space modulation is
designed in this work. Two high Q resonant modes exist in the cavity and follow separate …

The primary purpose of this thesis is to design a high quality factor (Q) and low mode volume
nanophotonic resonator which can be tuned using external stimuli, eg, voltage. Based on …
