Fast carrier dynamics in GaAs photonic crystals near the material band edge at room temperature
Ranojoy Bose, Jason S. Pelc, Charles M. Santori +2
We measure fast carrier decay rates (6 ps) in GaAs photonic crystal cavities with resonances near the GaAs bandgap energy at room temperature using a pump-probe measurement. Carrie…
All-optical coherent control of vacuum Rabi oscillations
Ranojoy Bose, Tao Cai, Kaushik Roy Choudhury +2
When an atom strongly couples to a cavity, it can undergo coherent vacuum Rabi oscillations. Controlling these oscillatory dynamics quickly relative to the vacuum Rabi frequency en…
Controlled coupling of photonic crystal cavities using photochromic tuning
Tao Cai, Ranojoy Bose, Glenn S. Solomon +1
We present a method to control the resonant coupling interaction in a coupled-cavity photonic crystal molecule by using a local and reversible photochromic tuning technique. We dem…
Spectroscopy of 1.55 m PbS Quantum Dots on Si Photonic Crystal Cavities with a Fiber Taper Waveguide
M. T. Rakher, R. Bose, C. W. Wong +1
We use an optical fiber taper waveguide to probe PbS quantum dots (QDs) dried on Si photonic crystal cavities near 1.55 m. We demonstrate that a low density (m$^…
Temperature-tuning of near-infrared monodisperse quantum dot solids at 1.5 um for controllable Forster energy transfer
Ranojoy Bose, James F. McMillan, Jie Gao +5
We present the first time-resolved cryogenic observations of Forster energy transfer in large, monodisperse lead sulphide quantum dots with ground state transitions near 1.5 um (0.…
Weak coupling interactions of colloidal lead sulphide nanocrystals with silicon photonic crystal nanocavities near 1.55 microns at room temperature
Ranojoy Bose, Xiaodong Yang, Rohit Chatterjee +2
We observe the weak coupling of lead sulphide nanocrystals to localized defect modes of 2-dimensional silicon nanocavities. Cavity resonances characterized with ensemble nanocrysta…
