Abstract

The authors report a study of the linear electro-optic coefficient in waveguides containing InGaAsGaAs quantum dots with a band gap at 1.3 μm. The Pockels effect is investigated in the 1.55 μm telecommunication window. The measured linear electro-optic coefficient for InGaAsGaAs is ∼3.4× 10-11 mV, much higher than that of the bulk or quantum well material. An ∼35% enhancement of the phase variation is achieved compared to that obtained in bulk GaAs waveguides. Finally, a spectral bandwidth of ∼100 nm is demonstrated in the 1.5-1.6 μm window.
