Abstract

We study a vertical-cavity surface-emitting laser with external feedback through a quarter-wavelength plate. We show that the effect of a rotation of the quarter-wavelength plate is to shift one comb of modes with respect to the other one. The dependence of the frequency on the rotation angle is calculated and shown to be in good agreement with experimental results.
