Abstract :
We have found cylindrical glass microtubes can be formed by vacuum assisted filtration using a micro-channel glass matrix followed by thermal treatment of the material. The microtubes are strongly luminescent and exhibit sharp whispering gallery modes. The ease of fabrication suggest that such photonic structures will find use as both microsensors and microlasers
