Ultrafast reflectivity modulation in AlGaAs/InAlGaAs multiple quantum well photonic crystal waveguides
A. Z. Garcia-Deniz, P. Murzyn, A. M. Fox +6
We report an ultrafast optical tuning of the reflectivity of AlGaAs/InAlGaAs multiple quantum well photonic crystal waveguides using a reflection geometry, pump-probe technique.
The dynamics of amplified spontaneous emission in CdSe/ZnSe quantum dots
D. O. Kundys, P. Murzyn, J. P. R. Wells +8
We have used the variable stripe technique and pump-probe spectroscopy to investigate both gain and the dynamics of amplified spontaneous emission from CdSe quantum dot structures.…
Resolution of Discrete Excited States in InGaN Multiple Quantum Wells using Degenerate Four Wave Mixing
D. O. Kundys, J. -P. R. Wells, A. D. Andreev +6
We report on two pulse, degenerate four wave mixing (DFWM) measurements on shallow InGaN/GaN multi-quantum wells (MQWs) grown on sapphire substrates. These reveal pulse length limi…
