Abstract
A method of forming an optical surface on an end portion of an optical fiber inserting the optical fiber through a ferrule bore of a ferrule so that the end portion extends past an end face on the ferrule. At least one laser beam is emitted from at least one laser and directed to the end face of the ferrule at a location spaced from the ferrule bore. The at least one laser beam is also directed at an angle relative to the end face of the ferrule so as to be incident on the end portion of the optical fiber after reflecting off the end face of the ferrule. The at least one laser is operated to cleave the end portion of the optical fiber, and the end face on the ferrule does not crack due to thermal expansion when the at least one laser is operated.
