Abstract:
1. An integrated circuit, comprising: a first logic module; a second logic module; and a coupled asymmetric quantum confinement structure communicatively coupling the first logic module to the second logic module, wherein the coupled asymmetric quantum confinement structure comprises: a first quantum confinement structure and a second quantum confinement structure, wherein each quantum confinement structure comprises a first cladding layer, an inner layer formed on the first cladding layer, a second cladding layer formed on the inner layer, an n+ region and a p+ region formed in the first cladding layer, and a first gate electrode formed on the second cladding layer, the n+ and the p+ regions to inject charge carriers into the inner layer and the first gate electrode being configured to deliver a first gate voltage, wherein the second quantum confinement structure is coupled in series with the first quantum confinement structure, wherein the second quantum confinement structure comprises at least one asymmetric physical dimension as compared to the first quantum confinement structure, and wherein the coupled first and second quantum confinement structures are capable of influencing a delay and/or frequency of an optical signal.
