Improving the Optical Quality Factor of the WGM Resonator
Resonators usually are characterized with two partially dependent values: finesse (ℱ) and quality factor (Q). The finesse of an empty Fabry-Perot (FP) resonator is defined solely by the quality of its mirrors and is calculated asℱ = πR1/2/(1 – R).

Embedded Telescope
Tiny telescopes have long been mounted on glasses to help visually impaired people perform tasks, such as driving. But many potential users have resisted using them due to their appearance, whereby the lens is mounted atop the regular lens or above the frame. Moreover, the magnified view through the telescope is narrow.
Now,...
