Abstract

<p>Ultrafast all-optical switches using an intersubband transition in a quantum well are being developed. A very deep potential well with a thickness of a few nm is needed to achieve a 1.55μm transition. We report the latest results for intersubband transition all-optical switches using two different material systems of InGaAs/AlAs/AlAsSb and CdS/ZnSe/BeTe.</p>
