Abstract: Within examples, a laser includes a first electrode and a second electrode; a first transport layer and a second transport layer that are between the first electrode and the second electrode; a gain layer positioned between the first transport layer and the second transport layer, where the gain layer comprises a material having a Perovskite crystal structure; and a substrate on which the first electrode, the second electrode, the first transport layer, the second transport layer, and the gain layer are formed, where a distributed feedback (DFB) waveguide is formed within the first transport layer, and where the laser is configured such that a current flowing through the gain layer between the first electrode and the second electrode causes the gain layer to emit coherent light. Examples also include methods for fabricating the laser, as well as additional lasers and methods for forming those lasers.
