Estimate of mode coupling in a spin-VECSEL
We study experimentally the nonlinear mode coupling between circular polarizations in a vertical-cavity surface-emitting laser (VCSEL) device developed for spin injection. The specific experimental arrangement that includes a Faraday rotator enables laser oscillation on left-circular or right-circular polarization, by adjusting the cavity losses. We show the simultaneous oscillation of both polarizations never occurs, proving that the Lamb coupling constant is very close to 1 in this VCSEL device, a situation that is ideal for spintronic applications.
