Description
Optical solitons and microresonator frequency combs offer a powerful platform for quantum communication, but their performance is critically determined by the underlying dispersion profile of the guiding structure. This work explores dispersion engineering strategies for integrated waveguides and ring resonators to realize controlled anomalous group-velocity dispersion suitable for soliton formation, low-distortion pulse propagation, and quantum state preservation [1].
Waveguide cross-sections are optimized to obtain smooth, weakly anomalous dispersion near the quantum channel wavelength, while accounting for realistic material dispersion and Kerr nonlinearity. This approach is extended to ring resonators, where geometric design and azimuthally modulated structures shape the integrated dispersion of cavity modes. The resulting engineered dispersion profiles support fundamental soliton propagation, dispersion-managed long-distance links, and microcavity Kerr solitons[2].
Design guidelines are provided for on-chip sources and channels tailored to time-bin and phase-encoded quantum communication protocols, enabling preservation of phase and photon-number correlations essential for quantum information processing.
