Description
Technical field
The present invention relates to micro optical element, system, especially relate to a kind of optical resonance cavity with micro-fiber optical loop.
Background technology
Optical resonator has been widely used in optical information processing, sensing, active device.The structure that realizes optical resonator at present mainly contains F-P chamber, microballoon resonant cavity, dish-type resonant cavity, optical fibre ring resonant cavity or the like.In recent years, along with the improvement of optical fiber preparation technology, low-loss micro-nano fiber is produced out, and is expected to be applied to micro-nano photonic propulsion device, improves the device integrated level.Optical resonator is exactly an example wherein.The method that obtains the fine optical resonator of low-light in the world mainly is that nano optical fibers is directly contacted by Van der Waals for and electrostatic force, forms annular or spirality resonant cavity.But Van der Waals for and electrostatic force all a little less than, these structures are all stable inadequately, are difficult to use in practice.
Summary of the invention
The object of the present invention is to provide a kind of optical resonance cavity with micro-fiber optical loop, utilize the high Q of micron diameter optical fiber preparation (quality factor) value ring junction resonant cavity.
The technical scheme that the present invention solves its technical problem employing is: make the ring junction resonant cavity with the low-light fibre.

Embodiment
Preparation process of the present invention is as follows:
(1) at first with drawing by high temperature farad system general single mode fiber, prepares the low-light fibre of 1-5 μ m; (2) utilize two conical fiber probes at light microscope lower-pilot low-light fibre, prepare the ring junction of diameter in the millimeter magnitude, an end of ring junction links to each other with monomode fiber, and an end is unsettled; (3) utilize micropositioning stage to strain free end gradually, the diameter that changes ring junction is to the scope that needs; (4) input wideband light source or tunable laser, the optical characteristics of measurement resonant cavity; (5) be placed on the ring junction resonant cavity on the different substrates or be immersed in the solution, measure its optical characteristics.
One of applicating example:
Use general single mode fiber drawing by high temperature method to prepare 2.66 μ m low-light fibres, prepare the ring junction resonant cavity of 396 μ m diameters under light microscope, then, the input tunable laser is measured resonance characteristic.Fig. 1 is a structural principle schematic diagram of the present invention; Fig. 2 is the enlarged drawing of knotting part A among Fig. 1, junction configuration as can be seen.Fig. 3 is the transmitted spectrum that the input tunable laser obtains in this ring junction air, calculates gained Q value and is about 10000, and fineness is 9.2.
Two of applicating example:
Use general single mode fiber drawing by high temperature method to prepare 1.73 μ m low-light fibres, prepare the ring junction resonant cavity of 850 μ m diameters, then it is immersed in the water, the input tunable laser is measured optical characteristics.Transmitted spectrum after accompanying drawing 4 ring junction resonant cavitys immerse in the water still has good resonance characteristic as can be seen in water, calculating gained Q value is 31100, and fineness is 13.
Different with ordinary optic fibre, low-light is fine because diameter is very little, and is suitable with the transmission light wavelength, so have portion of energy to transmit outside optical fiber with the form of evanescent wave in the transmission light time, make light when the zone of the knotting by being in contact with one another, interfere mutually, produce resonance by the evanescent wave coupling.
The present invention breaks into the fine knot resonant cavity that goes in ring of low-light the structure of knot, compare with the belt resonant cavity that forms of directly contacting by Van der Waals for and electrostatic force and to have extraordinary stability, be easy to control and adjusting, and can in the aqueous solution He on the low-refraction substrate, use.
Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection range of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
