Adaptive quantum design for QCSE devices and nanophotonic devices

摘要

A QCSE device may have a semiconductor quantum well structure, with an energy band profile defined by a broken-symmetry quantum well potential V(x). The quantum well potential V(x) may be identified by adaptive numerical searches performed by a processing system, which uses adaptive algorithms to numerically optimize the quantum well potential, so as to most closely match a desired optical response of the QCSE device to incident optical radiation. A nanophotonic device may include a plurality of dielectric scattering centers distributed within a substantially uniform medium in an aperiodic, broken-symmetry spatial configuration. The spatial configuration of the dielectric elements may be numerically computed and optimized using iterative techniques, so as to most closely generate a desired target function response from the nanophotonic device.
