Abstract:
The authors demonstrate a new route to the fabrication of individual aluminosilicate microtubes that
can act as micron-scale optical cylindrical resonators. The microtubes were prepared using a simple
vacuum assisted wetting and filtration through a microchannel glass matrix.
Microphotoluminescence spectra of the microtube cavity show sharp resonant modes with quality
factors up to 3200. A strong reduction of the emission decay time at high excitation power confirms
the occurrence of amplified spontaneous emission from a single microtube.
