Research paper : FIBER OPTIC CABLES FOR
... Most systems will require a fiber optic cable that can be connected and possibly disconnected, making bare cleaved fibers impractical. The traditional method of polishing the fiber ferrule is to use mechanical methods with finer grits on each polishing step. Following cleaving of the excess fiber ou ...

Optical tweezers
Optical tweezers (originally called ""single-beam gradient force trap"") are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch to physically hold and move microscopic dielectric objects similar to tweezers. Optical tweezers have been particularly successful in studying a variety of biological systems in recent years.
