Total Absorption in a Graphene Monolayer in the Optical Regime by Critical Coupling with a Photonic Crystal Guided Resonance
graphene photonic crystal near-infrared critical coupling guided resonance absorption enhancement
2014/8/6
We numerically demonstrate total absorption in graphene in the near-infrared and visible wavelength ranges by means of critical coupling with guided resonances of a photonic crystal slab. In this wave...

Chirped Microwave Photonic Filter High Frequency Tuning Capability
2011/5/21
A chirped single-bandpass photonic filter is proposed improving the delay performance achieved by microstrip structures. Frequency range is extended up to tens of GHz since carrier-suppression-effect ...

Intermodulation Harmonic Distortion Microwave Photonic Phase Shifters
2011/5/15
We theoretically and experimentally evaluate the harmonic and intermodulation distortion in a SFL phase shifter which comprises an EOM, a SOA under CPO regime and an optical filter.
Resonance-enhanced optical forces between coupled photonic crystal slabs
Modes Guided waves Optical forces
2010/8/10
The behaviors of lateral and normal optical forces between coupled photonic crystal slabs are analyzed. We show that the optical force is periodic with displacement, resulting in stable and unstable e...
Experimental demonstration of an all-optical analogue to the superradiance effect in an on-chip photonic crystal resonator system
all-optical analogue superradiance effect on-chip photonic crystal resonator system
2010/8/10
We show that an all-optical analogue to the Dicke superradiance effect can be observed in on-chip photonic crystal resonator systems where two resonators are separated by a distance much longer than t...

Optical resonances created photonic transitions
2010/8/10
We show that a high-Q optical resonance can be created dynamically, by inducing a photonic transition between a localized state and a one-dimensional continuum through refractive index modulation. In ...
Tuning the coherent interaction in an on-chip photonic-crystal waveguide-resonator system
coherent interaction on-chip photonic-crystal waveguide-resonator system
2010/8/10
We experimentally demonstrated that the characteristics of the coherent interaction between two waveguide-coupled resonators can be drastically tuned by changing the propagation phase in the waveguide...
Reducing spectral attenuation in solid-core photonic crystal fibers
Fiber optics optical communications Microstructured fibers
2010/6/10
We describe the effects of fabrication process timing and preform exposure to atmospheric air on spectral attenuation in photonic crystal fibers. The lowest attenuation is achieved by rapid processing...

Reconfigurable Silicon Photonic Lattice Filters Four Cascaded
2010/6/10
We present a fully-reconfigurable CMOS-compatible silicon-photonic lattice-filter with four cascaded unit cells consisting of resonant rings and Mach-Zehnder interferometers. The measurements show hig...
We present results of the IRIS project, a DARPA-MTO funded program to develop a router with an all-optical data plane and a total capacity of more than 100 Tb/s.
Photonic Spectral Processor Employing Two-Dimensional WDM Channel Separation and a Phase LCoS Modulator

2010/6/5
We propose and demonstrate a spectral phase and amplitude modulator spanning full 2D-space by crossing a 100GHz WGR and a 1200gr/mm bulk grating. We address individual WDM channels with high resolutio...
As AT&T plans for the future, there are a number of critical decisions required to define a new 100G backbone. These decisions are driven by specific carrier characteristics, which are described in th...
High Dynamic-Range Microwave Photonic Links using Maximally Linear FIR Optical Filters
Fiber optics links subsystems Frequency modulation
2010/6/4
We propose a microwave photonic link in which maximally linear FIR optical filters discriminate frequency modulation. Using a tenth-order filter, one can achieve a 127 dBm/Hz 2/3 SFDR with 1 mW of rec...
