“…The Thue-Morse PQC is constituted by Au nanopillars that find broad application in photonics. [24,[39][40][41][42][43] The geometrical lattice parameters are in the submicron scale, with a diameter of the nano-pillars of D PQC = 500 nm, a height of H PQC = 120 nm and lattice constant a = 710 nm (Figure 1j). The third structure is a square lattice metasurface (SQM), made of SiO 2 pillars characterized by a diameter D SQM = 300 nm, nominal height H SQM = 200 nm and periodicity equal to 1 μm (Figure 1n).…”

Bio‐inspired and biodegradable quantum optics scenarios constitute a pathway toward environmentally friendly front‐end technologies. Such an inspiring perspective necessitates the replacement of classic gain materials with a biological counterpart like photoluminescent bacteria. It is easy to imagine that, in this case, a planar and cell‐viable substitute of classic bulk solid‐states resonators can be highly beneficial. In this paper a micro‐ and nano‐photonic structuration of both a standard and a functionalized version of a typical bacterial growth medium (Luria‐Bertani Agar – LBA) is successfully realized. Three structures belonging to the categories of photonic crystals are replicated, such as quasi‐crystals and meta‐surfaces, demonstrating how the proposed media can be used as templates for high‐end photonic applications. The optical quality of the replicated structures is confirmed by far‐field diffraction measurements. The structured growth media allow for a broad control of the surface wettability by accessing a so‐called Wenzel state, in which the original hydrophilicity of a material is increased due to the photonic structuration. Finally, the suitability of the nano‐structured LBA as a plasmonic platform is evidenced. The proposed micro‐and nano‐structured photonic growth media constitute the first, fundamental step toward quantum optical frameworks from biological media.

“…Previous studies have demonstrated the widespread utilization of PCs in sensor production. While traditional twodimensional PCs sensors have shown remarkable performance in areas such as non-reciprocity and biochemical sensing, they still exhibit certain limitations and drawbacks [29,30]. Furthermore, these challenges are constrained by the limitations of structural design and cannot be fully addressed by the integration of various physical principles alone.…”

In this paper, a novel structure of magnetized plasma spherical photonic crystals is proposed that enables the development of sensors based on the evanescent wave principle. This sensor structure integrates a plasma with two isotropic media and applies periodic boundary conditions. Leveraging the principle of the evanescent wave, when the incident light is perpendicular to the interface of a medium with high optical density or thickness and the incident angle exceeds a critical angle, the transfer matrix method is utilized to compute the sharp peaks in the transmission spectrum. Subsequently, sensors produced using these sharp absorption peaks can detect the magnetic induction intensity, plasma frequency, and solution concentration of serum creatinine. The sensitivity and quality factors of these measurements are 8.35×1010 T-1, 3583, 1.5×10-4 (2πc/d)-1, 2970, 3.55, and 22824, respectively. Furthermore, a detection limit of 9.15502×10-6 RIU should be taken into account to ensure the normal operation of serum creatinine detection, satisfying the minimum requirements of biosensing.
