Abstract
The optical mixer (1) contains a polarization-maintaining length of optical waveguide (4) as a mixing element. The pump light (P) is coupled to the optical mixer in so that its plane of polarization makes an angle of 45.degree. with the principal axes of the length of optical waveguide (4). One advantage of this optical mixer (1) is that the optical power of the mixing product (M) depends not on the polarization of the signal light (S), but only on the phase relationship between signal light and pump light. The mixer can be used to advantage in an optical phase-locked loop.
