Whispering gallery mode(WGM)optical microcavities,which are capable of light field confinement and manipulation in a relatively small volume,have gained considerable attention from fundamentals in enhanced light-matte...
Control over excitation wavelengths,sample size,and doping concentrations in glassy materials with high levels of configuration entropy shows promises of efficient correlation between absorption and build-up of cohere...
Efficient ultra-broadband emitter is realized by using lanthanide ion doping coupled with“DPs-in-glass composite”(DiG)structure.The synergy of self-trapped exciton together with the energy transition induce this ult...
