The conventional WGM cavity is composed of homogeneous materials with a constant refractive index both in the core and cladding. The light field is confined in the cavity through the total internal reflection (TIR) and enhanced through constructive interference. The ultrahigh-Q factor has been realized in various dielectric WGM cavities with a large mode volume (V) and angular momentum.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2022-09-optical-black-hole-cavity-based.html\" target=\"_blank\" rel=\"nofollow noopener\">Researchers propose and demonstrate an optical black hole cavity based on transformation optics<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Whispering-gallery-mode (WGM) cavities represent an intriguing platform for intensely enhancing light-matter interaction.
