Extended Data Fig. 9: Comparison of electrically-driven integrated perovskite lasers with single-cavity and dual-cavity structures.
From: Electrically driven lasing from a dual-cavity perovskite device
a, Integrated perovskite laser based on a single-cavity structure. b, Integrated perovskite laser based on the dual-cavity structure. c, Histogram of current-density thresholds for the two types of perovskite lasers. d, Emission spectra of the perovskite lasers driven at a current density of 280 A cm−2. The measurements were performed at room temperature in air (temperature: ~22 °C, relative humidity: ~50%).
