Proposal for chip-scale generation and verification of photonic dimers

A semiconductor chip to generate photonic dimers, a quantum photonic state, is proposed and analyzed. The measurement scheme to validate the existence of dimers is also discussed. The design uses InAs epitaxial quantum dot structures coupled to weak laser pulses with the interaction tailored by a chiral nanophotonic waveguide. The performance is analyzed as a function of quantum dot misalignment. Greater than 50% excitation efficiency is still expected as long as the quantum dot is in the lower half of the chiral waveguide.
