Displacement-sensitive photonic crystal structures based on guided resonance in photonic crystal slabs
Displacement-sensitive photonic crystal structures guided resonance photonic crystal slabs
2015/8/11
We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain ...

2015/8/7
We present here ultra-compact high-Q Fano resonance filters with displaced lattices between two coupled photonic crystal slabs, fabricated with crystalline silicon nanomembrane transfer printing...
We show how to calculate the first- and second-order statistics of the scattered fields for an arbitrary intensity coherent-state light field interacting with a two-level system in a...
Ultracompact nonreciprocal optical isolator based on guided resonance in a magneto-optical photonic crystal slab

2015/8/10
We design an ultracompact optical isolator with normal incident geometry that operates with a bandwidth that is substantial for a device of this size. For operation in a telecommunication wavelength o...

temperature sensitivity tilted fiber Bragg grating plasmon resonance sensors
2013/5/27
A miniature surface plasmon resonance sensor is fabricated from a gold-coated standard optical fiber with an in-core tilted fiber Bragg grating fabricated by UV exposure. The sensor h...
Broadening Adjustable Range on Post-Fabrication Resonance Wavelength Trimming of Long-Period Fiber Gratings by Heating
Broadening Adjustable Range Post-Fabrication Resonance Wavelength Long-Period Fiber Gratings
2015/7/16
The adjustable range of resonance wavelengths of long-period gratings was broadened toward the blue side by heating, and the mechanism was studied. The large blue shift, 41 nm, was obtained by heating...
Analysis of guided-resonance-based polarization beam splitting in photonic crystal slabs
Analysis guided-resonance-based polarization beam splitting photonic crystal slabs
2015/8/10
We present an analysis of the phase and amplitude responses of guided resonances in a photonic crystal slab.Through this analysis, we obtain the general rules and conditions under which a photonic cry...
Omnidirectional resonance in a metal–dielectric–metal geometry
Omnidirectional resonance metal–dielectric–metal geometry
2015/8/11
We show that a planar metallic microcavity structure can exhibit an omnidirectional resonance, i.e.,a resonance for which the resonance wavelength is independent of the incidence angle of light. The s...
