Demonstration of Controlling the Spatiotemporal Dynamics of Optical Near-Field Excitation Transfer in Y-Junction Structure Consisting of Randomly Distributed Quantum Dots
Figure 1
(a), (b) Schematic illustration of optical excitation transfer from QD1 to QD2 via dressed photon interactions, where (a) shows the case where energy transfer occurs from QD1 to QD2 and (b) shows the case where control light is incident on QD2, thus suppressing energy transfer. (c) Schematic diagram of long-range optical excitation transfer system. Green and yellow circles represent QD1’s and QD2’s, respectively. (d) Schematic diagram of experimental model. Green and yellow regions represent groups of QD1 and QD2 structures consisting of randomly distributed QD1’s and QD2’s, respectively. (e) Energy diagram schematically showing the experimental model from point B to point A.
