Optical fibers with interferometric path length stability by controlled heating for transmission of optical signals and as components in frequency standards [PDF]

open access: yes, 2005
We present a simple method to stabilize the optical path length of an optical fiber to an accuracy of about 1/100 of the laser wavelength. We study the dynamic response of the path length to modulation of an electrically conductive heater layer of the ...
