“…To address this concern, a number of templating approaches have been investigated, which use the fabricated polymer or silica structures as templates for backfilling of high-refractive-index inorganic materials, followed by removal of the template, resulting in inverse 3D inorganic or semiconducting PCs (see detailed discussion in section ). Meanwhile, PCs with tunable band gaps offer promise in applications that do not require complete PBGs, such as reflective displays, , chemical/biological and optical sensors, − optical shutters, and active filters and polarizers. − For this purpose, polymeric or silica structures can be utilized through surface functionalization or a templating method. For example, we can engineer or tune the band gap by infiltrating functional materials, such as metallic or magnetic nanoparticles, − liquid crystals, ,, and stimuli responsive gels. ,,,− Regardless of the fabrication/backfilling approaches, it is critical to control materials chemistry to create desired 3D structures with preferred materials properties, for example, high refractive index, high transmission at the wavelength of interest, wide tunability, and high thermal and mechanical stability.…”

“…Because of their properties of photonic bandgap (PBG) and localization, 1 photonic crystals (PCs) have attracted a great deal of interest as the new type of optical materials used for developing novel mirrors, [2][3][4] waveguides, 5 cavities, 6 filters, [7][8][9] and sensors. 10 Recently, much attention has been paid to the properties of localized modes at defects of PCs.…”

In this work, we designed a narrow-band filter based on a one-dimensional photonic crystal heterostructure featuring an angle-adjustable single-channel. The design presented here is based on a quarter-wave reflector with a mirror defect layer in the middle of the structure. By combining two defective one-dimensional photonic crystals (PCs), we obtained a heterostructure in which the two sub-PCs had the wavelengths of their defect modes, that is, the same at one incident angle and different at all other incident angles. This structure possessed the single-channel resonant peak in the transmission spectrum under either a normal or an oblique incident angle, and the angle-adjustability was related to the two modifying parameters. The filter based on this heterostructure possessed not only a narrow passband but also a sharp angular pass breadth. These properties have potential applications in angular tunable, single-channel narrow-band filters.

“…When the half-power bandwidth of the filter is less than 0.001 nm (∆ λ 3dB < 0.001 nm) [ 30 , 31 ], the filter can be regarded as an UNBF. The Q factor of the defect resonance is defined as the center wavelength divided by the 3 dB power bandwidth [ 32 , 33 ].…”

In this paper, we present a high-efficiency narrow band filter (NBF) based on quasi-one-dimensional photonic crystal (PC) with a mirror symmetric heterostructure. Similarly to the Fabry-Perot-like resonance cavity, the alternately-arranged dielectric layers on both sides act as the high reflectance and the junction layers used as the defect mode of the quasi-one-dimensional PC, which can be designed as a NBF. The critical conditions for the narrow pass band with high transmittance are demonstrated and analyzed by simulation and experiment. The simulation results indicate that the transmission peak of the quasi-one-dimensional PC-based NBF is up to 95.99% at the telecommunication wavelength of 1550 nm, which agrees well with the experiment. Furthermore, the influences of the periodicity and thickness of dielectric layers on the transmission properties of the PC-based NBF also have been studied numerically. Due to its favorable properties of PC-based NBF, it is can be found to have many potential applications, such as detection, sensing, and communication.
