Abstract
The present disclosure is directed to a fiber optic bolometer device . In an implementation , a fiber optic bolometer device includes an optical fiber and a silicon layer that comprises a Fabry - Perot interferometer . The silicon layer includes a first surface and a second surface . The fiber optic bolometer device includes a reflective dielectric film disposed over the first surface of the silicon layer where the reflective dielec tric film is adjacent to an end face of the optical fiber . The fiber optic bolometer device also includes an absorptive coating disposed over the second surface of the silicon layer ( e . g . , the surface distal to the end face of the optical fiber ).
