Abstract
A precision alignment technique for polarisation-maintaining, fibres is described using a frequency modulated tunable laser in combination with phase sensitive detection. The effect of residual intensity modulation is overcome by detecting the signal at twice the modulation frequency. An alignment accuracy of better than 0.2 degrees was achieved.
