Abstract
Micromachining of single-mode telecommunication fibres (SMF28) was accomplished with a Nd:YAG laser at a wavelength of 355 nm. Micromachining is important for the manufacturing of Bragg gratings and long period gratings which are used in add-drop filters and wavelength division multiplexers. Manufacturing of miniature Fabry-Perot interferometers used for temperature sensors is also possible. A short overview of micromachining concepts is presented. The experimental setup, as well as the equipment used, is described. Alignment processes, focal point determination and centering of the laser beam onto the optical fibre are outlined. Micromachining results are presented.
