Fabry-Perot interferometer with quantum well mirror for controllable dispersion compensation

In this work we propose a controllable dispersion compensation mirror based on Fabry-Perot interferometer with quantum well. The choice of the parameters of the heterostructure and experiment geometry makes it possible to introduce negative dispersion in narrow spectral region with maintaining the constant reflection coefficient. Feasibility of this concept is proved experimentally by measurements of the reflectivity form InGaAs/GaAs quantum well. The control of quantum well exciton parameters could be used to switch the dispersion compensation on and off.
