Magnetic Quasi-Phase Matching All-Fiber Isolator

Figure 2

(a) shows an example of spectrum without (red) and with (green) application of a point stress. (b) shows the ratio of the spectra (red) and the fitting (green) to a cos² function. (c) shows the phase (red) of the cos² function at 1064 nm for 8 positions of the point stress and a fit to a straight line (green).
