Directivity of Multilayered Microlasers Featuring Silver Film and Distributed Bragg Reflectors

Year: 2026

Type: conference-paper

Abstract: The paper deals with the analysis of the directivity of microlaser structure made of silver film superstrate, active layer, and distributed Bragg reflector substrate. For purely electromagnetic analysis of such configurations we use the Lasing Eigenvalue Problem (LEP) approach in combination with the Transfer Matrix Method. The LEP is a semiclassical eigenvalue problem for an open optical cavity adapted for the presence of an active region, where the gain is represented by the negative imaginary part of the complex refractive index of material. Microlaser directivity is computed as the ratio of the difference between upward and downward radiated power to their sum. The obtained results highlight the impact of the Bragg reflector and the metal-film reflector parameters on the directivity.
