Measurements involving the phase of a light beam are employed in a variety of fields such as interferometry, phase contrast imaging, holography, coherent signal processing, quantum nondemolition measurements and quantum gates. It is, thus, of fundamental concern to examine the influence of a single emitter on the phase of a light beam. Usually this is performed using a high-finesse cavity coupled...
We report the implementation of a single-molecule optical transistor and show that it can coherently attenuate and amplify a freely propagating laser beam.
This work demonstrates stimulated emission from a single dye molecule and shows that it can coherently attenuate and amplify a freely propagating laser beam. The first report of stimulated emission from a single emitter in free space is presented and a single emitter can serve as a nanometer-sized optical transistor is shown.
The amplification of light by a single excited molecule in free space is demonstrated in this paper. The extinction effect is the result of a destructive interference between the incident laser beam and the coherently scattered light from the molecule in the ground state. Thus, inversion of the population should lead to a phase shift of the scattered light and amplification of the laser light.
In this paper, we propose a Krylov-subspace-based operator-exponential method for time-domain simulations of the Maxwell equations with general nonlinear polarizations. This includes (classical) chi(2)- or chi(3)- nonlinearities and/or nonlinear coupled system dynamics. As an illustration, we compare the performance of our approach to certain well-known methods for the case of pulse self-steepening...
Efficient coupling of laser to single quantum emitters is achieved via near- and far-field techniques. Direct detection of 11.5% extinction and the first direct measurement of the Mollow triplet in solid state system are demonstrated.
