Abstract
An optical multilayer mirror of a Fabry-Perot interferometer includes a reinforcing section provided as a side wall of each of second and fourth high refractive-index layers. The reinforcing section is configured to support a portion of each of the second and fourth high refractive-index layers covering a top surface of each of first and second low refractive-index layers and reach first and third high refractive-index layers via each of the first and second low refractive-index layers, respectively. Even when the first and second low refractive-index layers lack a mechanical strength with a high n ratio achieved by selecting materials for the first through fourth high refractive-index layers and the first and second low refractive-index layers, the reinforcing section helps prevent the second and fourth high refractive-index layers from being bent. The optical multilayer mirror thus features a wide high-reflectance band.
