A monolithic microcavity laser with simultaneous upconversion and frequency-doubled lasing via crystal-in-glass engineering
{{output}}
This work demonstrates a novel crystal-in-glass composite structure for multifunctional micro-nano light sources in integrated photonics. Based on a Er3+/Yb3+-codoped glass-ceramic (GC) whispering gallery mode (WGM) microcavity incorporating Ba2TiGe2O8 (BTG) c... ...
