UV-Nanoimprinted Distributed-Feedback Perovskite Lasing

This chapter comprises simulations from the manuscript:

Iakov Goldberg, Nirav Annavarapu, Simon Leitner, Karim Elkhouly, Fei Han, Niels Verhellen, Tibor Kuna, Weiming Qiu, Cedric Rolin, Jan Genoe, Robert Gehlhaar and Paul Heremans, “Multimode Lasing in All-Solution-Processed UV-Nanoimprinted Distributed Feedback MAPbI₃ Perovskite Waveguides”, [2]

The calculation of the modes is done in accordance to [1].

Fig. 16 Upper left: calculated dispersion relation prior to lasing, Upper right: intensity of the lasing mode in the near field, lower left: required DC gain for the lasing threshold, the dotted lines show the measured lasing lines at 3 different locations, lower right: far field lasing intensity as a function of the angle
