Metaphotonic Catalysis: Amorphous silicon metasurfaces encode photochemical activity
Elif Nur Dayi, Priscila Vensaus, Milad Sabzehparvar +3
Solar-to-fuel conversion can benefit from photoelectrodes with engineered light-matter interactions, yet most nanostructured designs provide limited control over the spatial and sp…
Photo-Thermally Tunable Photon-Pair Generation in Dielectric Metasurfaces
Omer Can Karaman, Hua Li, Elif Nur Dayi +2
Photon-pair sources based on spontaneous four-wave mixing (SFWM) in integrated photonics are often spectrally static. We demonstrate and model a fundamental thermo-optical mechanis…
Cross-polarized and Stable Second Harmonic Generation from Monocrystalline Copper
Elif Nur Dayi, Alan R. Bowman, Omer Can Karaman +2
Second-harmonic generation (SHG) is a powerful surface-specific probe for centrosymmetric materials, with broad relevance to energy and biological interfaces. Plasmonic nanomateria…
Decoupling Optical and Thermal Responses: Thermo-optical Nonlinearities Unlock MHz Transmission Modulation in Dielectric Metasurfaces
Omer Can Karaman, Gopal Narmada Naidu, Alan R. Bowman +2
Thermo-optical nonlinearities (TONL) in metasurfaces enable dynamic control of optical properties like transmission, reflection, and absorption through external stimuli such as las…
