An efficient all-optical switch using a lambda atom in a cavity QED system
We propose an all-optical switch constructed from a two-mode optical resonator containing a strongly coupled, three-state system. The coupling allows a weak laser drive to incoherently control the transmission of a much stronger signal laser into (and through) the resonator. We demonstrate that in this simple setup the presence of a control drive with 1/10 the power of the signal drive can indu...
متن کاملSingle-photon all-optical switching using waveguide-cavity QED
This manuscript demonstrates switching of a single signal photon by a single gating photon of a different frequency, via a cross-phase modulation. This effect is mediated by materials exhibiting electromagnetically-induced transparency (EIT), which are embedded in photonic crystals (PhC’s). An analytical model based on waveguide-cavity QED is constructed for our system, which consists of a PhC ...
متن کاملInvestigations of a coherently driven semiconductor optical cavity QED system
Chip-based cavity quantum electrodynamics QED devices consisting of a self-assembled InAs quantum dot QD coupled to a high quality factor GaAs microdisk cavity are coherently probed through their optical channel using a fiber taper waveguide. We highlight one particularly important aspect of this all-fiber measurement setup, which is the accuracy to which the optical coupling level and optical ...
متن کاملring resonator coupled m-z all-optical switch by using a pumped nonlinear directional coupler
we propose a new ring resonator side-coupled m-z interferometer all-optical switch throughthe pumped nonlinear directional coupler. by controlling pump power p to lead the coupler reflectivityr approaching to 1, the resonator finesse will be enhanced dramatically, and then the minimumswitching power in silica-based practice devices can be obtained. as a sample, we use a nonlinearcoupler made by...
متن کاملAll-optical crossbar switch using wavelength division multiplexing and vertical-cavity surface-emitting lasers.
A design for an all-optical crossbar network utilizing wavelength-tunable vertical-cavity surface-emitting laser (VCSEL) technology and a combination of free-space optics and compact optical waveguides is presented. Polymer waveguides route the optical signals from a spatially distributed array of processors to a central free-space optical crossbar, producing a passive, all-optical, fully conne...
