Coherent contributions to population dynamics in a semiconductor microcavity

March 29, 2022
Jagannath Paul, Hendrik Rose, Ethan Swagel, Torsten Meier, Jared Wahlstrand, Alan Bristow
Multidimensional coherent spectroscopy (MDCS) is used to separate coherent and incoherent many-body contributions to the population-time dynamics in a GaAs-based semiconductor microcavity encapsulating a single InGaAs quantum well. In a three-pulse four

Analysis of complex multidimensional optical spectra by linear prediction

October 27, 2021
Ethan Swagel, Jagannath Paul, Alan Bristow, Jared Wahlstrand
We apply Linear Prediction from Singular Value Decomposition (LPSVD) to the analysis of two-dimensional complex optical spectra. LPSVD is a non-iterative procedure that fits time-domain complex data to the sum of damped sinusoids, or Lorentzian peaks in
