Spatio-temporal coherent molding and retrieval of pulsed signals in optical waveguides
Nika Durishvili, Ramaz Khomeriki, Vakhtang Jandieri +3
Optical waveguides are key elements for high fidelity, long distance optical communications. Coupled waveguide arrays allow for higher information density, steerting the propagatio…
Linear Amplification of Optical Signal in Coupled Photonic Crystal Waveguides
Vakhtang Jandieri, Ramaz Khomeriki
We introduce a weakly coupled photonic crystal waveguide as a promising and realistic model for all-optical amplification. A symmetric pillar type coupled photonic crystal waveguid…
Nonlinear All Optical Digital Amplification of the Light Pulse in Weakly Coupled Photonic Crystal Waveguides
Vakhtang Jandieri, Ramaz Khomeriki
All-optical amplification of the light pulse in a weakly coupled two nonlinear photonic crystal waveguides (PCWs) is proposed. We consider pillar-type PCWs, which consist of the pe…
Self-Chaotization in Coupled Optical Waveguides
Ramaz Khomeriki, Archil Ugulava, Levan Chotorlishvili
We consider theoretically two coupled optical waveguides with a varying barrier height along the waveguides direction. The barrier could be constructed by the elongated island with…
Driving light pulses with light in two-level media
Ramaz Khomeriki, Jerome Leon
A two-level medium, described by the Maxwell-Bloch (MB) system, is engraved by establishing a standing cavity wave with a linearly polarized electromagnetic field that drives the m…
Bistable light detectors with nonlinear waveguide arrays
Ramaz Khomeriki, Jerome Leon
Bistability induced by nonlinear Kerr effect in arrays of coupled waveguides is studied and shown to be a means to conceive light detectors that switch under excitation by a weak s…
