Beschreibung
Zusammenfassung:	An electro-absorption modulator 100 including a quantum well 102 configured to provide a variable electromagnetic absorption spectrum in response to an applied electric field, wherein the quantum well is a type-II quantum well comprising two material layers, each material layer having a graded material composition, such that the potential in each material layer varies as a function of position.
