Abstract

A new method of forming a fiber optic device having optical properties is provided. The method includes the sequential, substantially simultaneous or sequence independent steps of applying energy to heat at least one region of at least one optical fiber or optical fiber device using at least one energy source positioned a predetermined distance therefrom, resulting in the deformation of the heated at least one optical fiber or optical fiber device, and monitoring at least one of the optical properties of the at least one optical fiber or optical fiber device. The method also includes the steps of controlling at least one of the energy and the shaping or deforming, responsive to the monitoring step prior to completion of the method, and producing the at least one optical fiber or optical fiber device responsive to the controlling step.
