【Abstract】 The relation between the optical output power and the facet reflectivities for semiconductor lasers is analyzed. The results of numerical calculation show that the optimum optical output power can be obtained by controlling the reflectivities of the front and rear facets coated with dielectric films. In addition, the analyzed results show that the output power are greatly increased as cavity losses, stripe width and active region thickness are decreased.更多还原
