Reseña. Silicon nitride microring resonators: Classical and quantum applications.

During the last decade, optical frequency combs have had a significant impact in the fields of precision metrology and astronomy. In more recent years, silicon nitride (SiN) mirroring resonators (MRR) have proven to be a useful platform for the miniaturization of these frequency comb sources. This research expands the knowledge in this field in two directions. Firstly, from the classical point of view, it explores the use of SiN MRRs for the generation of a single cavity soliton. In this area, we reported cavity soliton formation and its corresponding frequency comb with high coherence and low-intensity noise. Also, we were able to observe the intra-cavity field showing a single pulse of 74 fs through time-domain measurements. Furthermore, we were able to generate a single cavity soliton breather, and we demonstrated a 7T phase shift between the oscillation of the pump and the comb lines. Secondly, from the quantum point of view, this project investigates SiN MRRs as a source of entangled photon pairs for quantum information processing technologies. In this direction, we have reported a source of comb-shaped entangled photon pairs, also called biphoton frequency combs, on a chip. The pairwise energy-time entanglement verification and the potential use of this source in quantum communications have been demonstrated using Franson interferometry and nonlocal dispersion cancellation, respectively. To show that the generated entangled photons are in a coherent superposition of frequency bins, we used a biphoton frequency comb with 50 GHz free spectral range and used a phase modulation technique to overlap contiguous frequency bins, creating indistinguishability and interference patterns. This novel high-dimensional frequency-bin entangled source of photon pairs has a potentially high impact in areas like quantum computing and quantum communications due to its low cost, robustness, compactness, and scalability.
