“…Thus, many articles focus on the modification of radiation losses via changing the structures of photonic resonators including grating, Fabry Pérot cavity, and metal-DBR structures. In these cases, the Q and T are manipulated but limited by varying the radiation loss only (e.g., grating, Fabry Pérot cavity, and metal-DBR structures can only reach the T of 70%, 55%, and 48% and the Q of 19, 14 and 54 respectively) [21], [24]- [26]. This limitation hampers the application implementations such as liquid crystal display [26].…”

Achieving High Transmission and Q Bragg Filter via Balancing Dissipation and Radiation Loss

Simultaneously high quality-factor (Q) and transmission (T) are highly desired in various optical, photonic, and optoelectronic applications such as filters, sensors, photodetectors and lasers. However, a trade-off between high Q and high T exists widely in optical systems thanks to the different physics triggers underneath. Here, as an example, we experimentally demonstrate a Bragg filter composed of niobium pentoxide (Nb2O5) and silica (SiO2) stacks which enable high Q of 183 and high T of 91.3%. Balancing dissipation and radiation rate of the optical system is crucial to the performance of the device, which is validated by modulating the absorption of material (Nb2O5) and the number of stacks. Further, with the principle the tunable Bragg filter is able to work in a similar way at optical wavelengths, i.e., maintaining almost unchanged FWHM (full width at halfmaximum) and T values. We believe our work offers an efficient strategy for achieving high Q and T optical systems to meet diversified application requests.

“…The metal-based emitters those have been implemented to achieve narrowband thermal emission in MIR regime, include metal-insulator-metal metamaterials, [21][22][23][24][25] diffractive gratings, [26] bull's eye structures, [27] nanochannels [28] and Tamm-plasmon-polaritons multilayered structures. [29][30][31][32] Metalinsulator-metal metamaterials and nanochannels exhibit low quality-factor (Q < 25) due to the intrinsically higher optical loss and non-radiative damping of metals. Diffractive gratings and bull's eye structures could improve the efficiency of thermal emission (Q ≈ 100).…”

Tailoring the absorption/emission through nanostructures from broadband to narrowband has attracted increasing attention due to the merits of high efficiency and compactness. However, most of the reported narrowband emitters require either complex fabrication process or thick coating of the suitable materials (~mm). In this paper, by exciting Berreman mode through a combination of Au mirrors and ultra‐thin layers of low‐loss uniaxial/biaxial anisotropic 2D van der Waals polar crystal hBN/α‐MoO3, a narrowband absorption/emission peak is realized in the mid‐infrared region. The measured quality‐factor of Berreman mode for hBN/Au and α‐MoO3/Au structure can reach up to 134 and 164, respectively. The deep subwavelength thickness (~nm) and bilayer architecture simplify the fabrication process. Furthermore, taking advantage of the in‐plane birefringence originating from α‐MoO3, the polarization of the absorbed/emitted radiation can be controlled through this planar configuration. Such ultrathin narrowband absorbers/emitters provide new opportunities for the advancements in thermal sources, infrared sensors, and thermophotovoltaic power generation systems.

“…Recently, among multilayer structures, Tamm plasmon polaritons (TPP)-based 1D structures have garnered increasing attention as thermal emitters [ 38 , 39 , 40 , 41 , 42 ]. The TPP surface waves exist at the interface between a metallic mirror and distributed Bragg reflector (DBR) and have a zero in-plane wave vector and strong energy confinement [ 43 ].…”

Thermal emitters with properties of wavelength-selective and narrowband have been highly sought after for a variety of potential applications due to their high energy efficiency in the mid-infrared spectral range. In this study, we theoretically and experimentally demonstrate the tunable narrowband thermal emitter based on fully planar Si-W-SiN/SiNO multilayer, which is realized by the excitation of Tamm plasmon polaritons between a W layer and a SiN/SiNO-distributed Bragg reflector. In conjunction with electromagnetic simulations by the FDTD method, the optimum structure design of the emitter is implemented by 2.5 periods of DBR structure, and the corresponding emitter exhibits the nearly perfect narrowband absorption performance at the resonance wavelength and suppressed absorption performance in long wave range. Additionally, the narrowband absorption peak is insensitive to polarization mode and has a considerable angular tolerance of incident light. Furthermore, the actual high-quality Si-W-SiN/SiNO emitters are fabricated through lithography-free methods including magnetron sputtering and PECVD technology. The experimental absorption spectra of optimized emitters are found to be in good agreement with the simulated absorption spectra, showing the tunable narrowband absorption with all peak values of over 95%. Remarkably, the fabricated Si-W-SiN/SiNO emitter presents excellent high-temperature stability for several heating/cooling cycles confirmed up to 1200 K in Ar ambient. This easy-to-fabricate and tunable narrowband refractory emitter paves the way for practical designs in various photonic and thermal applications, such as thermophotovoltaic and IR radiative heaters.
