Abstract
A method of setting an apparent optical length of an optical fiber for a given optical wavelength includes heating the trimmed optical fiber to selectively vary a refractive index thereof in response to comparison of a determined arrival phase angle with a reference value representing a desired arrival phase angle to change the determined arrival phase angle so that a difference between the desired and determined arrival phase angles does not exceed an acceptable tolerance of a phase error.
