Microlasers have experienced tremendous development in the past decade and become an
essential part in laser evolution, as miniature lasers provide strong optical confinement and …

An overview of the formation of calcium phosphate under in vitro environment on the surface
of a range of bioactive materials (eg from silicate, borate, and phosphate glasses, glass …

Whispering‐gallery modes (WGM) on a spherical surface were first described by Lord
Rayleigh at the beginning of the last century, but only after the invention of laser did they …

Confinement of light into small volumes has become an essential requirement for photonic
devices; examples of this trend are provided by optical fibers, integrated optical circuits …

Whispering gallery mode (WGM) microresonators, thanks to their unique properties, have
allowed researchers to achieve important results in both fundamental research and …

Whispering gallery mode (WGM) microcavities have a small mode volume, a high quality (Q)
factor and great application potential in the field of integrated optics. The coupling of light …

Whispering-gallery mode (WGM) cavities formed by dielectric structures have attracted
intensive interest in various fields. The high-quality factor and smaller mode volume …

In this review paper some recent advances on optical fiber sensors are reported. In
particular, fiber Bragg grating (FBG), long period gratings (LPGs), evanescent field and …

Optical microcavities with ultralong photon storage times are of central importance for
integrated nanophotonics. To date, record quality (Q) factors up to 10 11 have been …

We describe a novel method for making microbottle-shaped lasers by using a CO2 laser to
melt Er: Yb glass onto silica microcapillaries or fibres. This is realised by the fact that the two …
