Optics Express, 2010 We theoretically study a 1D elastic photonic crystal containing air voids as an opto-pneumatic medium. This medium is sensitive to weak deviations of the external pressure and, owing to its elasticity, can vary its geometry depending on the external conditions.

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Advanced Functional Materials, EarlyView.Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Maxwell Fish-Eye and Half-Maxwell Fish-Eye Based on Graded Photonic Crystals
IEEE Photonics Journal, 2018 We report on the design of the Maxwell fish-eye based on graded photonic crystals. It is a radially graded refractive index structure, whose remarkable property is to form perfect images in the sense of geometrical optics.

Advanced Functional Materials, EarlyView.The polymer wall stabilized dye‐doped liquid crystals (PWLCs) enhance the sensitivity of photoinduced molecular reorientation in dye‐doped LC systems. The PWLC with an invisible polymer wall successfully reduces the threshold intensity and functions as an optical limiter under the incidence of low intensity light laser source.

Macroscopic photonic single crystals via seeded growth of DNA-coated colloids
Nature Communications, 2023 Photonic crystals—a class of materials whose optical properties derive from their structure in addition to their composition—can be created by self-assembling particles whose sizes are comparable to the wavelengths of visible light.

Tapered photonic crystal microcavities embedded in photonic wire waveguides with large resonance quality-factor and high transmission [PDF]
, 2008 We present the design, fabrication, and characterization of a microcavity that exhibits simultaneously high transmission and large resonance quality-factor (Q-factor). This microcavity is formed by a single-row photonic crystal (PhC) embedded in a 500-nm-
