Single quantum dot spectroscopy using a fiber taper waveguide near-field optic
Kartik Srinivasan, Andreas Stintz, Sanjay Krishna +1
Photoluminescence spectroscopy of single InAs quantum dots at cryogenic temperatures (~14 K) is performed using a micron-scale optical fiber taper waveguide as a near-field optic.…
Multiple quantum wells for passive ultra short laser pulse generation
R. Quintero-Torres, E. Vazquez-Ceron, E. Rodriguez-Rodriguez +2
Solid state lasers are demanding independent control in the gain media and cavity loss to achieve ultra short laser pulses using passive mode-locking. Recently, laser mode-locking…
Cavity Q, mode volume, and lasing threshold in small diameter AlGaAs microdisks with embedded quantum dots
Kartik Srinivasan, Matthew Borselli, Andreas Stintz +2
The quality factor (Q), mode volume (Veff), and room-temperature lasing threshold of microdisk cavities with embedded quantum dots (QDs) are investigated. Finite element method sim…
