Abstract
A emitter is formed of a thin-film membrane disposed within a cavity so as to provide a output beam. The emitter may be configured to obtain broadband light. The emitter may enhance the emissivity of light over a broad spectral band.
Claims20
An emitter comprising a thin-film membrane disposed within a cavity so as to provide an output beam, wherein the cavity is configured such that transmissivity through the cavity substantially matches an absorption of the thin-film membrane.
An emitter comprising a thin-film membrane disposed within a cavity so as to provide a broadband output beam, wherein one or more of a transmissivity through the cavity and an absorption of the thin-film membrane is configured to provide enhanced power output of the broadband output beam.
