In the form of an optical resonator, the structure includes two, multi-layer, aperiodic dielectric mirrors and a lossy, dielectric thin film and characterized by an intrinsic optical absorption over at least a one octave bandwidth. The two, multi-layer, aperiodic dielectric mirrors are characterized by a reflectivity amplitude that increases in-step with increasing wavelength over the at least one octave bandwidth. Upon a single incoherent beam of optical radiation having a spectrum over the at least one octave bandwidth incident on one side of the resonator structure, the lossy, dielectric thin film is characterized by an effective optical absorption over the at least one octave bandwidth that is greater than the intrinsic optical absorption over the at least one octave bandwidth."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Incoherently-induced coherent perfect absorption (CPA) apparatus, method, and applications thereof","description":"A thin film photonic structure that enables segregation of the effective absorption of the thin film and its intrinsic absorption while substantially eliminating bandwidth restrictions.
