Resonance-enhanced optical forces between coupled photonic crystal slabs
Modes Guided waves Optical forces
2015/8/10
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
2015/8/10
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 by photonic transitions
Optical resonances created photonic transitions
2015/8/10
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 ...

Reconfigurable Silicon Photonic Lattice Filters Four Cascaded
2015/6/10
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.
High Dynamic-Range Microwave Photonic Links using Maximally Linear FIR Optical Filters
Fiber optics links subsystems Frequency modulation
2015/6/4
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...
