n-GaAs microcavity as an efficient Faraday rotator

par PEPS - publié le

Faraday rotation up to 19◦ in the absence of an external magnetic field is demonstrated in an n-type bulk GaAs microcavity under circularly polarized optical excitation. This strong effect is achieved because (i) the spin-polarized electron gas is an efficient Faraday rotator and (ii) the light wave makes multiple round trips in the cavity.
