Abstract
A method of characterizing processed optical fiber ends using second-harmonic generation (SHG) is disclosed. The method includes sequentially irradiating micro-volumes within the end section with a focused laser beam of wavelength λL; sequentially detecting respective amounts the SHG light emitted from the respective micro-volumes; correlating the amounts of the detected SHG light with respective amounts of stress; and determining one or more optical properties of the end section of the optical fiber based on the amounts of stress. The optical fiber being measured can be held in a ferrule. The stress in the optical fiber end section can be due to processing the optical fiber end using laser and/or mechanical means.
