We observed energy transfers among quantum dots dynamically. The energy transfer occurs from smaller to larger quantum dots in 150 ps and is applicable to the nanophotonic buffering device. OCIS codes: (230. 3990) Microstructure devices; (999.9999) Optical Near Field Energy transfers among quantum dots enable several unique nanophotonic devices, such as an AND-gate [1], NOT-gate [2], an optical nanofountain [3], an optical nano content addressable memory (CAM) [4] , and an optical digital to

In this paper, we show the experimental results of time-resolved near-field spectroscopy and discuss the energy transfers among quantum dots. The experimental results have indicated the delay time coming from the energy transfer is applicable to the novel optical buffer. (b) (a) a2460_1.pdf CFE3.pdf
