What is a photonic biosensor?
Photonic biosensors: SPR and beyond These are self-integrated devices that use specific biorecognition elements—such as antibodies, DNA strands or enzymes—to capture and detect a target molecule, or analyte, present in a sample.
What is photonic crystal laser?
A two-dimensional (2-D) photonic-crystal laser consists of top layers of contact and clad fused to the active gain medium on which the photonic-crystal lattice is constructed. The light wave propagates in four directions and forms 2-D standing waves.
Do photonic crystals absorb light?
For example, we have demonstrated a multi-layer photonic crystal composed of titanium dioxide and silicon, which exhibits significant absorption efficiency in the optical spectrum of wavelength between 440nm and 640nm.
Who invented photonic crystal fibers?
Philip St. J. Russell
Acronym: PCF (also used for polymer cladded fibers!) Pioneered by the research group of Philip St. J. Russell in the 1990s, the development of photonic crystal fibers and the exploration of the great variety of possible applications have attracted huge interest.
What is the most widely used photonics tool?
FIMMWAVE/FIMMPROP is probably the most widely used propagation tool for the modelling of silicon photonics: rigorous (no slowly varying approximation), fully vectorial, offering wide angle capability and very high design flexibility.
What is PCF sensor?
A PCF-based sensor typically consists of a transparent core surrounded by cladding of lower refractive index (air holes). The light is retained inside the core based on the total internal reflection, however the internally reflected light actually penetrates, for a small distance, into the cladding region.
What are four applications of photonics?
Applications of Photonics Economically significant uses of photonic devices include fiber optic telecommunications, optical data storage, displays, optical pumping of high-power lasers and laser printing.
