A complete architecture of integrated photonic circuits based on AND and NOT logic gates of exciton-polaritons in semiconductor microcavities

摘要

In this letter we introduce a complete photonic logic gate architecture,making use of the non-linear and spintronic properties of exciton-polaritons insemiconductor microcavities. This hybrid light-matter design is highly compactand offers the advantages expected of photonic circuits including: nodistance-dependent loss or signal gradation; electrical isolation and immunityto electromagnetic interference; reduced error-checking overhead; and directcoupling to external light, useful for fibre optic communication.
