Abstract
The present disclosure relates to the fabrication and characterization of an optical fiber capable of firing light virtually from any point along its circumferential surface. The optical fiber is preferably prepared by laser micromachining. In preferred embodiments, laser radiation is focused onto a multimode optical fiber axis, forming a conical-shaped cavity (side window) in the fiber core. Because of the total internal reflection when the laser beam reaches the side window-outside medium interface, the beam is reflected to the side of the optical fiber.
