Abstract:	We present the results of studies on small photonic microtube structures of less than 10 microns diameter. A new technique based on vacuum assisted filtration is used to produce the microtube resonantors. Whispering gallery modes are probed through the photoluminescence emission from the glass material forming the cavity. We observe resonances with polarized emission having quality factors up to 3000. These microresonator structures exhibit a large evanescent field which makes them interesting for potential photonic applications.
