Abstract

We demonstrate monolithic AlGaAs sources generating high dimensional frequency-entangled states in the telecom band at room temperature. The reflectivity and dispersion properties of our devices allow producing qudits with d of several tens.

The investigation and use of integrated frequency comb sources (i.e. featured by equally-spaced discrete spectral modes) have recently provided a unique framework to address the challenges of generation and coherent manipulation of complex quantum states in on-chip devices. We exploit integrated frequency combs for generating entangled photon pairs, as well as multi-photon states, and high-dimensional (D-level, i.e. quDit) entangled photons. In particular, we manage to coherently manipulate such complex quantum systems by using telecommunications components (standard fiber telecom).
