Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering
Advanced Photonics Research, Volume 6, Issue 5, May 2025.Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create

Advanced Photonics Research, Volume 6, Issue 5, May 2025.Microfabrication using nano‐ to micron‐sized blocks has transformative potential for next‐gen electronics, optoelectronics, and materials. Traditional methods are limited by scalability and precision. STIC, a single‐laser system for precise colloid manipulation and immobilization using femtosecond lasers, is introduced that enables efficient 3D ...

The detailed optics of photonic nanojets generated by normal plane-wave incidence on dielectric cylinders is discussed. These nanojets have a subwavelength beam waist and propagate with little divergence for several wavelengths. A physical explanation for this peculiar behavior is presented.

Hybrid materials for optics and photonics
Chemical Society Reviews, 2011The interest in organic-inorganic hybrids as materials for optics and photonics started more than 25 years ago and since then has known a continuous and strong growth. The high versatility of sol-gel processing offers a wide range of possibilities to design tailor-made materials in terms of structure, texture, functionality, properties and shape ...

Silicon photonics: optical modulators [PDF]
SPIE Proceedings, 2010 Silicon Photonics has the potential to revolutionise a whole raft of application areas. Currently, the main focus is on various forms of optical interconnects as this is a near term bottleneck for the computing industry, and hence a number of companies have also released products onto the market place.

Photon Statistics in Adaptive Optics
Optics and Photonics News, 1999ABSTRACT Random aberrations due to atmospheric turbulence determine the angular resolution of ground-based telescopes. Adaptive optics systems compensate the wavefront degradation before detection. Although systems with a large number of subapertures in the wavefront sensor and of actuators in the deformable mirror provide the best results, they are ...

An acousto-optic architecture is presented to implement a nonblocking space-division switch with O(N) complexity. Signal degradation is minimal so that the switch is suitable for nonregenerative application within optical networks; it is also capable of rapid reconfiguration. Experiments for a 1 x 4 switch show an insertion loss ranging from 4.6 to 5.6

Early Photon Optical Tomography
Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006Fluorescence tomography is an emerging tool for functional and molecular imaging of tissues. Inversion is however complicated by the high scattering that photons experience when propagating through tissue that reduces resolution. While continuous wave systems offer implementation simplicity, time-resolved systems offer the ability to improve resolution

Optical nonlinearity in photonic glasses
Journal of Materials Science: Materials in Electronics, 2005A brief review of optical nonlinearity in photonic glasses is given. For third-order nonlinearity, the relationship between two-photon absorption and nonlinear refractive index is considered using a formalism developed for crystalline semiconductors.
