Embodiment Construction
[0032] The present invention will be further described below in conjunction with specific examples.
[0033] Step 1. Device preparation: According to the optical fiber preparation method of the embodiment, a single-fiber optical tweezers based on an air defect microcavity is manufactured. The optical fiber of the device is a five-core optical fiber. Since the five-core optical fiber contains more cores, a larger air defect microcavity is required to fully modulate the conduction mode field in the optical fiber (see Figure 2). A tunable laser with a pigtail plus a fiber coupler 101, 102 is used to inject light into the device in conjunction with a common single-mode fiber (see figure 1 , Figure 9 ).
[0034] Step 2. Preparation of tapered fiber ends (this step can be prepared in two ways): hot-melt tapering: according to the fusion tapering method of the embodiment to make a parabolic tapered structure (see Figure 3); optical fiber fiber end grinding: According to the metho...
