Abstract

There has been much attention on the optical process of optical microcavities.¹ Optical microcavity is useful for the efficient nonlinear optical devices. This is because that the strong optical field confined in a high-Q microcavity enhances the nonlinear optical interactions. Semiconductor planner microcavity is a good candidate to demonstrate the enhanced optical nonlinearity. We present experimental results with a GaAs single quantum well in a half-wavelength microcavity. To clarify the microcavity effect, we tune the exciton resonance energy around the fixed cavity resonance, by using quantum confined Stark effect (QCSE).²
