Definitions

  • Glass capillary tubes useful for a thermometer, transportation of a fluid, sensors or other applications have been produced directly from molten glass.
  • a fine glass capillary tube having an inner diameter of from 0.1 to 0.2 mm useful as a ferrule for optical fibers in recent years has been produced by hot stretching the glass capillary tube directly produced from molten glass as mentioned above.
  • the capillary tube produced directly from molten glass as mentioned above is used as the starting preform, whereby it is extremely difficult to bring the inner diameter to a level of about 1/10 of the outer diameter.
  • Microcavity resonators including one dimensional structures utilizing distributed Bragg reflectors, spherical microcavities, microdisk and microcylindrical laser emitters have been previously reported.
  • resonant cavities that can store and recirculate electromagnetic energy at optical frequencies have many useful applications, including lasing, high-precision spectroscopy, signal processing, sensing, and filtering.
  • Optical microcavity resonators have quality factors (Qs) that are higher by several orders of magnitude, as compared to other electromagnetic devices. Maximum measured Qs as large at 10 10 have been reported, whereas commercially available devices typically have Qs ranging from about 10 5 to about 10 7 . The highest Q resonances encountered in these microcavities are due to optical whispering-gallery-modes (WGM) that are supported within the microcavities.
  • WGM optical whispering-gallery-modes
  • microspheric cavities have the potential to provide unprecedented performance in numerous applications.
  • these microspheric cavities may be useful in applications that call for ultra-narrow linewidths, long energy decay times, large energy densities, and fine sensing of environmental changes, to cite just a few examples.
  • the substrate matrix may be selected from any one or more of porous silicon, microchannel glass, alumina and a polymer membrane.
  • the polymer membrane comprises any one or more of polycarbonate, polystyrene, PVC, polyethylene and polypropylene.
  • the micro- or nano-sized product is in the form of a xerogel or glass fibre, tube or capillary.
  • the product has a length of up to several ( ⁇ 10) millimetres.
  • the invention also provides a micro-optical device comprising a microtube or microcapillary coupled to a microsphere.
  • the resultant homogenous solution was hydrolysed by adding the mixed solution of H 2 O, C 2 H 5 OH and HCl in the molar ratio 4: 1: 0.011 per mole of alkoxide.
  • the fibres have an approximate length of 100 ⁇ m and a diameter of 2-3 ⁇ m.
