Monolithically integrated circuits for Optical injection locking of ring lasers with QKD and QPSK applications
Optical injection locking of integrated ring lasers promises to be a key technology of the future, but it is still lacking experimental verification. In this paper we present two monolithically integrated photonic circuits that experimentally realize Optically injection locking of ring lasers. The presented circuits pave the way for future application in Quantum Key Distribution and coherent communication
