Wideband Dispersion Flattening for Whispering Gallery Mode Microresonators Fabricated by Laser Micromachining

Dispersion engineering of microresonators is very important for applications, such as optical comb generation which desires wideband flat and small dispersion. In this paper, dispersion investigation has been carried out for whispering gallery mode (WGM) microresonators fabricated by laser micromach...
