Controllable optical analog to electromagnetically induced transparency in coupled high-Q microtoroid cavities.
We experimentally demonstrate an all-optical analog to electromagnetically induced transparency (EIT) on chip using coupled high-Q silica microtoroid cavities with Q-factors above 10(6). The transmission spectrum of the all-optical analog to EIT is precisely controlled by tuning the distance between the two microtoroids, as well as the detunings of the resonance frequencies of the two cavities.
متن کاملTuning all-Optical Analog to Electromagnetically Induced Transparency in nanobeam cavities using nanoelectromechanical system
We report the observations of all-optical electromagnetically induced transparency in nanostructures using waveguide side-coupled with photonic crystal nanobeam cavities, which has measured linewidths much narrower than individual resonances. The quality factor of transparency resonance can be 30 times larger than those of measured individual resonances. When the gap between cavity and waveguid...
متن کاملAll-optical analog to electromagnetically induced transparency in multiple coupled photonic crystal cavities.
We report first observations of deterministic phase- and resonance-controlled all-optical electromagnetically induced transparency in multiple coupled photonic crystal cavities. The full-range tuning of coherently coupled cavity-cavity phase and resonances allow observations of transparency resonance in dark states with lifetimes longer than incoherently summed individual cavities. Supported by...

متن کاملOptical properties of electromagnetically induced transparency
A review of electromagnetically induced transparency is given. A semiclassical Hamiltonian is used to show that atomic coherence can inhibit absorption and enhance dispersion in the adiabatic limit. Experimental demonstrations and applications are discussed. The nonadiabatic effects are derived in the c-number Langevin formalism, and shown to give rise to correlate the phase of two incident fie...
