Miniaturized optical microwave source using a dual-wavelength whispering gallery mode laser
Résumé
We report on the observation of a compact optical microwave source based on a whispering gallery mode laser. The use of a single 160 µm diameter Erbium doped glass microsphere and two half fiber tapers allows a dual single mode laser emission around 1550 nm to be obtained. The generated beat note at 10,86 GHz has a linewidth of 22 kHz. This preliminary experimental demonstration shows the potentialities of Erbium doped whispering gallery mode resonators for microwave generation.
