Active whispering- gallery- mode optical microcavity based on self- assembled organic microspheres

摘要

The self-assembled organic microspheres of (E)-3-(4-(dip-tolylamino)phenyl)-1-(4-fluoro-2-hydroxyphenyl)prop-2-en-1-one (DTPHP) are fabricated, which serve as active WGM resonators. In addition, a dispersion relationship between the group refractive index (n(g)) and wavelength () is revealed to demonstrate the strong light-matter interaction inside the WGM microcavity with a maximum n(g) to be 7.7.
