A new extension of photonics is biophotonics, which involves a fusion of
photonics and Biology. Biophotonics deals with interaction between light and
biological matter. The use of photonics for optical diagnostics, as well as for light-activated and light-guided therapy, will have a major impact on health care. This is not surprising since Nature has used biophotonics as a basic principle of life from the beginning. Harnessing photons to achieve photosynthesis and conversion of photons through a series of complex steps to create vision are the best examples of biophotonics at work. Conversely, biology is also advancing photonics, since biomaterials are showing promise as new photonic media for technological applications. As an increasingly aging world population presents unique health problems, biophotonics offers great hope for the early detection of diseases and for new modalities of light-guided and light-activated therapies. Lasers have already made a significant impact on general, plastic, and cosmetic surgeries. Two popular examples of cosmetic surgeries utilizing lasers are skin resurfacing (most commonly known as wrinkle removal) and hair removal. Laser technology also allows one to administer a burst of ultrashort laser pulses that have shown promise for use in tissue engineering. Furthermore, biophotonics may produce retinal implants for restoring vision by reverse engineering Nature's methods.

When was Journal of Biophotonics created?
Journal of Biophotonics was created in 2008.
How does Biophotonics work?
Biophotonics is the use of beams of light in order to detect and treat cancer. It has fewer side effects than radiation treatments and can more accurately target cancerous tissue. It is a newer technology that is still being studied.
What is the time domain method of determining stability of a control system system?
Finite-difference time-domain (FDTD) is a popular computational electrodynamics modeling technique. It is considered easy to understand and easy to implement in software. Since it is a time-domain method, solutions can cover a wide frequency range with a single simulation run.The FDTD method belongs in the general class of grid-based differential time-domain numerical modeling methods. The time-dependent Maxwell's_equations(in Partial_differential_equationform) are discretized using central-difference approximations to the space and time partial derivatives. The resulting finite-difference equations are solved in either software or hardware in a leapfrog manner: the electric field vector components in a volume of space are solved at a given instant in time; then the magnetic field vector components in the same spatial volume are solved at the next instant in time; and the process is repeated over and over again until the desired transient or steady-state electromagnetic field behavior is fully evolved.The basic FDTD space grid and time-stepping algorithm trace back to a seminal 1966 paper by Kane Yee in IEEE Transactions on Antennas and Propagation (Yee 1966). The descriptor "Finite-difference time-domain" and its corresponding "FDTD" acronym were originated by Allen_Taflovein a 1980 paper in IEEE Transactions on Electromagnetic Compatibility (Taflove 1980). See "References" for these and other important journal papers in the development of FDTD techniques, as well as relevant textbooks and research monographs.Since about 1990, FDTD techniques have emerged as primary means to computationally model many scientific and engineering problems dealing with Electromagnetic_waveinteractions with material structures. As summarized in Taflove & Hagness (2005), current FDTD modeling applications range from near-DC (ultralow-frequency geophysics involving the entire Earth-ionosphere waveguide) through Microwaves(radar signature technology, Antenna_(radio), wireless communications devices, digital interconnects, biomedical imaging/treatment) to Visible_light( Photonic_crystal, nanoplasmonics, solitons, and biophotonics). In 2006, an estimated 2,000 FDTD-related publications appeared in the science and engineering literature (see "Growth of FDTD publications"). At present, there are at least 27 commercial/proprietary FDTD software vendors; 8 free-software/ Open_source-softwareFDTD projects; and 2 freeware/closed-source FDTD projects, some not for commercial use (see "External links").http://en.wikipedia.org/wiki/Finite-difference_time-domain_method
