Summary: A multi-channel transmitter with high-speed VCSELs locked by an optical frequency comb is proposed, achieving a 2-fold increase in frequency response and a 2.6 x 10(4)-fold reduction in linewidth. Single-lane transmission at 14-Gb/s over 20 km single-mode fiber is demonstrated without dispersion compensation, showing the potential for high-capacity transmission.

Summary: The researchers have found that the frequency degree of freedom of optical photons can be used for efficient quantum information processing. They have developed an integrated photonic platform for the generation and parallel processing of quantum frequency combs. Through the implementation of cavity-enhanced parametric down-conversion with Sagnac configuration, they were able to generate quantum frequency combs with identical spectral distributions. They also achieved on-chip quantum interference of different frequency modes using the same photonic circuit. This work provides a critical step towards the implementation of efficient quantum information processing with integrated photonics using the frequency degree of freedom.

Summary: In this work, we conducted a theoretical investigation on the dispersion relationship of microsphere cavities based on the theory of microcavity dispersion. The results revealed that the size of the microcavity corresponding to the zero dispersion point of the higher order mode is larger than that of the lower order mode at a certain wavelength. By utilizing mode coupling, we successfully achieved optical frequency comb in microsphere cavities with a diameter as small as 105 micrometers, with total dispersions in the normal dispersion region.

Summary: We study the multipartite quantum steering generated by the nonlinear process of three-photon parametric down-conversion in an optical cavity. The genuine quadripartite quantum steering can be obtained in this nonlinear process, and the stability of quadripartite quantum steering can be improved by injecting a signal. By considering the quantum property of the pump, we show that quadripartite quantum steering can be produced in the case of three-photon spontaneous parametric down-conversion. We also discuss the quantum steering properties in different seed configurations, which has potential applications in quantum information processing.

Summary: This paper proposes and investigates the generation of reconfigurable multiple-frequency (MF)-spaced MF-offset flat optical combs using an electro-optic (EO) multiple-parallel phase modulator (MP-PM). The technique allows flexible control of the frequency spacing and offset of the generated comb through EO modulation, without the need for optical filters. The driving conditions for achieving MF-spaced and MF-offset comb generation with spectral flatness are analytically clarified and summarized in simple formulas. Repartitioning of the modulator arms is also discussed for higher conversion efficiency in flexible comb generation.

Summary: This article proposes two schemes for generating a broadband optical frequency comb (OFC) source using dual laser sources. The first scheme involves using cascaded single-drive Mach-Zehnder modulator (MZM) and dual-drive Mach-Zehnder modulator (DD-MZM), while the second scheme replaces the single-drive MZM with a phase modulator (PM). Simulation results confirm the feasibility of these schemes.

Summary: This study presents a detailed experimental investigation on the effects of external optical injection on a Fabry Perot laser in both CW mode and gain switched mode. It explores the optimization of operating conditions to improve system performance for dedicated applications, and investigates the performance of the externally injected laser for optical frequency comb generation. The study demonstrates the generation of an OFC with specific spectral range and wavelength tunability, and presents the trade-off between bandwidth and phase noise of the generated OFC under external injection.

Summary: Kerr comb generation is usually achieved by the nonlinear dynamics of the intracavity field in a whispering-gallery-mode resonator pumped by a continuous-wave laser. This study focuses on the dynamics of Kerr optical frequency combs when pumped by a synchronous pulse train, emphasizing the impact of pump-cavity desynchronization on the spectral shape of the output combs. The proposed model based on the extension of the Lugiato-Lefever equation successfully accounts for the pulsed nature of the pump and the mismatch between the resonator's free-spectral range and the repetition rate of the pulse train.

Summary: This study introduces a high-gain, narrowband, all-polarization-maintaining fiber Brillouin amplifier to address the low power issue of single lines in optical frequency combs (OFCs). Numerical simulations and experiments are conducted to investigate the amplification process for an individual OFC line. The study demonstrates the direct generation of a Watt-level single-mode laser from an OFC, achieving the highest power, signal-to-noise ratio, and side-mode-suppression ratio reported to date.
