Summary: The emergence of photonic crystal biosensors is driven by the strong light limitation and adjustment of structural parameters in photonic crystals, resulting in sensors that are highly sensitive to low refractive index changes with small sensing areas. The rising importance of label-free biosensors is attributed to the utilization of emerging optofluidic technology.

Summary: This study develops the concept of a metahouse chamber for multiple band noise insulation, using a ventilated structure based on the idea of metamaterial systems. Broad stop-bands are achieved through strong coupling between pairs of Helmholtz resonators in the structure, demonstrating an averaged transmission attenuation of -18.6 dB within the spectral range from 1500 to 16 500 Hz both numerically and experimentally. The sparseness of the structure and the possibility of using optically transparent materials suggest the potential for partial optical transparency depending on the arrangement of structural elements.

Summary: Photonic moire lattices provide a platform for manipulating light, and there is strong interest in understanding how moire effects can be tailored in compact optical technologies. In this work, we map the moire effects of one-dimensional photonic moire lattices composed of width-modulated silicon nanowires and demonstrate various behaviors by tailoring parameters such as crystal size, symmetry, and moire fringe phase.

Summary: The strong confined electromagnetic field in micro/nano photonic structures provides new opportunities for studying the interaction between light and matter, enabling reversible or irreversible energy exchange between photons and emitters at the micro/nano scale by designing optical modes. Recent advances in strong coupling based on micro/nano photonic structures will have significant impact on the research of quantum nanophotonics and on-chip quantum devices.

Summary: The article discusses the properties of a recently introduced photonic crystal parametric oscillator, which achieves Canonical Resonant Four-Wave-Mixing by allowing only four (three in the degenerate case) modes of the cavity to interact through this parametric process. The study includes a statistical analysis of over 100 resonators and 10 parametric oscillators, assessing their robustness against fabrication tolerances and evaluating their performance in terms of average values and dispersion. The article also highlights the minimum pump power at threshold and the relationship between the cavity photon lifetime and three photon absorption as conditions for parametric oscillation.

Summary: We investigate the effect of an external magnetic field with arbitrary direction on the photonic band of a superlattice structure comprising alternating dielectric and magneto-optical plasma layers. By considering the electrodynamical anisotropy of the superlattice in the presence of the magnetic field, we derive the dispersion equations and observe that the photonic spectrum of the superlattice splits into two branches due to the magnetic field. Interestingly, our results show that a previously photo-isolating superlattice can become entirely photo-conducting, regardless of the direction of the applied magnetic field. These findings could be useful for the design and construction of new optical diode-like devices.
