Evidence of large high frequency complete phononic band gaps in silicon phononic crystal plates
We show the evidence of the existence of large complete phononic band gaps (CPBGs) in two-dimensional phononic crystals (PCs) formed by embedding cylindrical air holes in a solid plate (slab). The PC
High-Q micromechanical resonators in a two-dimensional phononic crystal slab
By creating line defects in the structure of a phononic crystal (PC) made by etching a hexagonal array of holes in a 15 μm thick slab of silicon, high-Q PC resonators are fabricated using a
Ultra-high Q planar silicon microdisk resonators for chip-scale silicon photonics.
While substrate leakage loss has warranted the necessity of substrate undercut structures in the past, it is shown here that the substrate has a very useful role to play for both passive chip-scale device integration as well as active electronic device integration.
Non-volatile holographic storage in doubly doped lithium niobate crystals
Photorefractive materials are being widely investigated for applications in holographic data storage. Inhomogeneous illumination of these materials with an optical interference pattern redistributes
High quality planar silicon nitride microdisk resonators for integrated photonics in the visible wavelength range.
High quality factor microdisk resonators are demonstrated in a Si(3)N(4) on SiO(2) platform at 652-660 nm with integrated in-plane coupling waveguides with critical coupling to several radial modes.
Compact wavelength demultiplexing using focusing negative index photonic crystal superprisms.
Here, we demonstrate a compact photonic crystal wavelength demultiplexing device based on a diffraction compensation scheme with two orders of magnitude performance improvement over the conventional
Properties of the slab modes in photonic crystal optical waveguides
We show that by placing a slab of semiconductor material between two photonic bandgap (PBG) mirrors, waveguide modes at frequencies out of the PBG can be obtained. These modes are similar to the
Optimization of metallic microheaters for high-speed reconfigurable silicon photonics.
Structural and material optimizations are carried out through heat transport modeling to improve the reconfiguration speed of metallic microheater devices, and the results are experimentally verified.
Two-center holographic recording
We describe a two-center holographic recording method for the storage of persistent holograms in doubly doped lithium niobate crystals. We use a two-center model, and we show that our experimental
Analysis of slitless holographic spectrometers implemented by spherical beam volume holograms.
It is shown that the slitless volume holographic spectrometer is not sensitive to the incident angle of the input beam for the practical range of applications, and it is believed it is a good candidate for portable spectroscopy for environmental and biological applications.
