In whispering gallery spherical micro-resonators, phase matching of second harmonic generation depends on the radius of the sphere. This unusual dependence causes the illustrated bending for the amplitude of the coupling coefficient between the fundamental and second harmonic modes shown here as a f
Schematic picture indicating the approximate time scales for energy flow in plant lightharvesting complex of photosystem II (LHC-II), a pigment-protein complex that carries over 50% of plant chlorophylls (Chl-a molecules contributing to the final energy acceptor state in green, other Chl-a in blue,
A wave-chaos lasing mode in a stadium-shaped microcavity, obtained by numerical computation. Two-dimensional microcavity lasers are rich in fundamentally interesting spatio-temporal optical phenomena. They also present new ways to control direction and power of laser emissions, with possible applica
## Optical-fiber microcoil waveguides and resonators and their applications for interferometry and sensing Recent progress in the theoretical and experimental studies of optical-fiber microcoil waveguides and resonators as well as their various applications are reviewed. In particular, the focus is
