Self-trapping of light and nonlinear localized modes in 2D photonic crystals and waveguides [PDF]
, 2001 We overview our recent results on the nonlinear localized modes in two-dimensional (2D) photonic crystals and photonic-crystal waveguides. Employing the technique based on the Green function, we describe the existence domains for nonlinear guided modes ...

Advanced Functional Materials, EarlyView.The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Defect modes in defective one dimensional parity-time symmetric photonic crystal
Scientific Reports, 2023 The introduction of defect layers into one-dimensional parity-time (PT) symmetric photonic crystals gives rise to resonances within the photonic bandgaps. These resonances can be effectively explained by our generalized temporal coupled mode theory.

Observation of Enhanced Beaming from Photonic Crystal Waveguides
, 2008 We report on the experimental observation of the beaming effect in photonic crystals enhanced via surface modes. We experimentally map the spatial field distribution of energy emitted from a subwavelength photonic crystal waveguide into free-space ...

Realization of 2-dimensional air-bridge silicon photonic crystals by focused ion beam milling and nanopolishing [PDF]
, 2006 We report the design and fabrication of small photonic crystal structures which are combined with conventional dielectric ridge waveguides. We describe in details the fabrication of both rough and smooth membranes, which are used as host for photonic ...

Advanced Functional Materials, EarlyView.This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Physical and Chemical Preparation Techniques and Applications of Photonic Crystals: A Review
CrystalsPhotonic crystals, which are important functional materials, are formed by the periodic arrangement of materials with different dielectric constants that have photonic bandgaps and localization properties. Their preparation methods are primarily physical
