Coupled asymmetric quantum confinement structures

A method for producing a coupled asymmetric quantum confinement structure, the method comprising:

• providing a substrate;
• depositing a first cladding layer on the substrate;
• depositing an inner layer on the first cladding layer, a first portion of the inner layer being associated with a first quantum confinement structure and a second portion of the inner layer being associated with a second quantum confinement structure, the second portion comprising at least one asymmetric physical dimension as compared to the first quantum confinement structure, and the first and second quantum confinement structures being capable of influencing a delay and/or frequency of an optical signal;
• depositing a second cladding layer on the inner layer;
• forming an n+ region and a p+ region in a first region of the first cladding layer, the n+ region and the p+ region in the first region of the first cladding layer to inject charge carriers into the inner layer;
• and
• forming a first gate electrode that is configured to deliver a gate voltage to the first quantum confinement structure.
