Wide bandwidth and high resolution planar filter array based on DBR-metasurface-DBR structures
Optics Express, 2016 We propose and experimentally demonstrate a planar array of optical bandpass filters composed of low loss dielectric metasurface layers sandwiched between two distributed Bragg reflectors (DBRs). The two DBRs form a Fabry-P rot resonator whose center wavelength is controlled by the design of the transmissive metasurface layer which functions as a ...

Self‐Hybridized Exciton‐Polariton Photodetectors From Layered Metal‐Organic Chalcogenolates
Advanced Functional Materials, EarlyView.Self‐hybridized exciton‐polariton photodetectors are demonstrated using high refractive index mithrene, eliminating the need for top mirrors. This simplified architecture enables tunable sub‐bandgap photodetection via lower exciton‐polariton states and enhanced carrier transport through ultrafast polariton group velocities.
