技术领域Technical field
本申请涉及光学元件技术领域，特别涉及一种复合结构微瓶透镜的制备方法及复合结构微瓶透镜。The present application relates to the technical field of optical elements, and in particular to a preparation method of a composite structure microbottle lens and a composite structure microbottle lens.
背景技术Background technique
复合结构的微瓶透镜，早期名称有纺锤节微纤维、微瓶谐振腔等，属于纤维和光学微腔领域，其中纺锤节微纤维在集水、油水分离、微流控、自清洁等领域应用广泛，而微瓶谐振腔在延迟线、微激光器、非线性光学、光机械、传感等领域具有重要的应用。与本发明最相近似的实现方案，最早的制备方法是本人于2013和2014年提出的(专利号：ZL201310268542.2；Applied Optics,2014,53:7819-7824)。其中在发明专利“ZL201310268542.2”中，是依托裸光纤或者微光纤制备光学胶贴剂的微瓶谐振腔，所用材料为美国Norland公司生产的NOA 61光学胶贴剂，其用途为制作回音壁膜光学微谐振腔器件，制备方法是通过一根半锥形光纤将NOA 61光学胶贴剂液滴滴入标准单模光纤或者热拉法形成的全锥光纤的锥腰处，液体表面张力和粘滞力效应在裸光纤或者微光纤上形成单个的瓶子形微谐振腔；在发表文章“Applied Optics,2014,53:7819-7824”中，同样使用Norland公司生产的NOA 61光学胶贴剂，依托熔融拉锥形成的微光纤，利用胶贴剂在微光纤上的润湿和液体表面张力作用在微光纤上自组装的形成连续多个瓶子形结构的光学微谐振腔，其应用领域也是回音壁膜光学微腔。Composite structure microbottle lenses, whose early names include spindle section microfibers, microbottle resonant cavities, etc., belong to the field of fibers and optical microcavities. Among them, spindle section microfibers are used in fields such as water collection, oil-water separation, microfluidics, and self-cleaning. Widely used, microbottle resonators have important applications in delay lines, microlasers, nonlinear optics, optomechanics, sensing and other fields. The earliest preparation method that is most similar to the present invention was proposed by me in 2013 and 2014 (Patent No.: ZL201310268542.2; Applied Optics, 2014, 53:7819-7824). Among them, the invention patent "ZL201310268542.2" is a microbottle resonant cavity that relies on bare optical fibers or microfibers to prepare optical adhesive patches. The material used is NOA 61 optical adhesive patches produced by the American Norland Company. Its purpose is to make echo walls. The film optical micro-resonant cavity device is prepared by dropping droplets of NOA 61 optical adhesive patch into the tapered waist of a standard single-mode optical fiber or a full-taper optical fiber formed by a thermal drawing method through a semi-tapered optical fiber. The surface tension of the liquid and The viscous force effect forms a single bottle-shaped micro-resonant cavity on bare fiber or micro-fiber; in the published article "Applied Optics, 2014, 53:7819-7824", NOA 61 optical adhesive produced by Norland Company was also used. Relying on the micro-fiber formed by molten tapering, the wetting of the adhesive on the micro-fiber and the surface tension of the liquid are used to self-assemble on the micro-fiber to form an optical micro-resonant cavity with multiple continuous bottle-shaped structures. Its application field is also echo. Wall membrane optical microcavity.
现有技术的缺点主要是：1)因为所做器件均应用于光学微腔器件，因此所述光学胶贴剂的限定条件较为严格，通常需要宽的透光带宽、低的光衰减率且在光照射下具有低收缩和固化后具有高硬度等特性；2)采用的方法是用一根半锥形光纤将微液滴滴入一根全锥光纤来形成微瓶谐振腔，显然滴入方式需要借助液滴的重力来克服微光纤的粘附力，因此微液滴不能太小，否则无法从半锥形微光纤中脱离出来；3)由于是依托全锥光纤让附着于微光纤上的光学胶贴剂液体自然断裂并收缩形成微瓶谐振腔，不能施加外部的人为控制，因此所形成的微瓶谐振腔个数和尺寸无法掌控。The main shortcomings of the existing technology are: 1) Because the devices are all used in optical microcavity devices, the optical adhesives have strict limitations, usually requiring a wide light transmission bandwidth, a low light attenuation rate, and It has the characteristics of low shrinkage under light irradiation and high hardness after curing; 2) The method used is to use a semi-tapered optical fiber to drop micro droplets into a full-tapered optical fiber to form a microbottle resonant cavity. Obviously the dripping method It is necessary to use the gravity of the droplets to overcome the adhesion force of the microfiber, so the microdroplets cannot be too small, otherwise they cannot be separated from the semi-tapered microfiber; 3) Because it relies on the full-tapered fiber to allow the microfiber to adhere to the The optical adhesive liquid naturally breaks and shrinks to form a micro-bottle resonant cavity, which cannot be controlled externally. Therefore, the number and size of the formed micro-bottle resonant cavities cannot be controlled.
