Photonic crystal fibers are a special types of optical fibers that has contain air holes distributed in specific patterns around a solid or hollow core. Due to their high sensitivity, inherent flexibility, and small diameters, they can be used in a variety of situations requiring high robustness and portability.
Photonic crystals occur in nature in the form of structural coloration and animal reflectors, and, as artificially produced, promise to be useful in a range of applications. Photonic crystals can be fabricated for one, two, or three dimensions. One-dimensional photonic crystals can be made of thin film layers deposited on each other.
Potential applications include cloaking and transformation optics. [10] Photonic crystals differ from PM in that the size and periodicity of their scattering elements are larger, on the order of the wavelength. Also, a photonic crystal is not homogeneous, so it is not possible to define values of ε (permittivity) or u (permeability). [11]
Dispersion of light (photons) by a prism. Photonics is a branch of optics that involves the application of generation, detection, and manipulation of light in the form of photons through emission, transmission, modulation, signal processing, switching, amplification, and sensing.
Unlike electronic integration where silicon is the dominant material, system photonic integrated circuits have been fabricated from a variety of material systems, including electro-optic crystals such as lithium niobate, silica on silicon, silicon on insulator, various polymers, and semiconductor materials which are used to make semiconductor lasers such as GaAs and InP.
This journal covers research in experiment, theory, and applications of photonic crystals and photonic band gaps. Additionally, the journal focuses on topics concerning the development of faster telecommunications and the transition from computer-electronics to computer-photonics. Coverage also includes the general topic of fabrication of ...
Photonic Sensors publishes original, peer-reviewed articles that report on new developments of interest to members of the photonics and sensor communities in all fields of photonic-sensing science and technology, including but not limited to topics on: Optical fiber sensors; Planar waveguide sensors; Laser-based sensors
Biomedical sensing: small size, low cost, and low power consumption offer a variety of advantages in biomedical sensing applications. Potentially, liquid-crystal lasers could form the basis for "lab on a chip" devices that provide immediate readings without sending a sample away to a separate lab.
