Simulation of time-resolved THz spectroscopy experiments
In a recent paper in Journal of the Optical Society of America B we have reported on the numerical analysis of a time-resolved terahertz (THz) spectroscopy experiment using a modified finite-difference time-domain method. Using this method, we show that ultrafast carrier dynamics can be extracted with a time resolution smaller than the duration of the THz probe pulse and can be determined solely by the pump pulse duration. Our method is found to reproduce complicated two-dimensional transient conductivity maps exceedingly well, demonstrating the power of the time-domain numerical method for extracting ultrafast and dynamic transport parameters from time-resolved THz spectroscopy experiments.
The basis of the work in that paper is a Matlab-based simulation tool written by Casper Larsen, who was the Master student carrying out the vast majority of the work in the project. We have decided to make the code freely available. If you fill out the form below (name, email, and organization type) you will get access to a file containing the necessary code, a short user manual, and short tutorials with instructive examples to illustrate the use of the code.
Figure 2 shows an example of the agreement between experiment (left) and simulation (right) which is possible with the simulation tool that you can download below. Do you want to be able to model your time-resolved THz spectroscopy experiments with high precision? Then fill out the form below, press submit, and download the package for Matlab!
