1. Lei, Szu-chin. Precision Mechanical Grinding Integrated with Spin-on-Glass Electrostatic Pulling Method for Producing Micro-hyperboloid Lensed Optical Fibers.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2016, NSYSU

A novel approach is presented for producing hyperboloid microlens structure directly on an optical single-mode fiber for enhancing the coupling efficiency between high-power laser diodes and single-mode fiber. The hyperboloid lens structure was directly produced with a flat-end single-mode fiber with the core diameter of 6.6 μm. The production has three-step process, including a precision mechanical grinding, a spin-on-glass coating and an electrostatic pulling process. After a single-mode fiber was grinded into hyperboloid shape, trace amount of spin-on-glass is attached to the grinded fiber tip and then an electrostatic pulling is used to adjust the radius of curvature of around 4-5 μm for the single-mode fiber endface. The hyperboloid microlens structure is manufactured for matching with the rectangular outlet of the semiconductor laser diode. A high average coupling efficiency around 81% is obtained, and highest reaches 86.42% for 20 produced lensed fibers. While using the produced hyperboloid fibers, which is doubled efficiency compared to the flat end fiber. The approach was saving time with a simple way of making a microlens structure, so that we testing the micorlenses stability to confirm the feasibility. The coupling stability in five minutes for 5 individual hyperboloid fibers not more than 0.17%, express the good stability for the produced hyperboloid microlensed fibers. Unlike previous with melting or other processes to forming a microlens structure, this method does not damage the fiber endface and can be re-produced. So that, the developed method provides a solution for producing hyperboloid microlensed fibers for high performance coupling between the single mode fiber and the semiconductor diode laser.
