F. Reynaud et E. Delaire, LINEAR OPTICAL-PATH MODULATION WITH LAMBDA 200 ACCURACY USING A FIBERSTRETCHER/, Electronics Letters, 29(19), 1993, pp. 1718-1719
The Letter reports the experimental generation of a linear optical pat
h modulation of 20 lambda range with an accuracy of lambda/200 (lambda
= 633nm) using a servo control system driving an optical fibre stretc
her. The error signal is provided by mixing interferometric signals wi
th an electronic oscillator.
