Senior Independent Study
Hyperbolic microlens fabrication
Fiber microlens which provides an efficient coupling mechanism as to match the spot size of the diode laser to the fiber, is commonly used for optical alignment. In this study, we proposed a new scheme of a tapered hyperbolic-end fiber (THEF) microlens. The THEFs have demonstrated up to 86% coupling efficiency which is more than 20% better than the hemispherical-end fiber microlenses.
