A coupled asymmetric quantum confinement structure (300) comprises first and second quantum confinement structures (302,322), such as quantum wells or quantum dots, where the first and second structures differ in at least one physical dimension such as width (320, 324), and are coupled in series. The coupled structure (300) is capable of influencing a delay and/or frequency of an optical signal, and can be used as a component in photonic integrated circuits. The first and second structures (302, 322) may be formed on a common substrate (31 1 ).. |
