Abstract

In this letter we introduce a complete photonic logic gate architecture, making use of the non-linear and spintronic properties of exciton-polaritons in semiconductor microcavities. This hybrid light-matter design is highly compact and offers the advantages expected of photonic circuits including: no distance-dependent loss or signal gradation; electrical isolation and immunity to electromagnetic interference; reduced error-checking overhead; and direct coupling to external light, useful for fibre optic communication.
