Summary: In this paper, a polarization-multiplexed system capable of generating stable optical frequency combs with tunable frequency differences is presented. The polarization dynamics of a dual-frequency comb generated from a single mode-locked Er-doped fiber laser are experimentally studied. The obtained results will extend the application to areas such as polarization spectroscopy and dual-comb-based polarimetry.

Summary: Optical frequency combs (OFCs) are a type of light source that consists of equally spaced coherent spectral lines. Electro-optic frequency combs (E-O combs) have unique advantages such as tunable repetition rate, high sidebands power, and reconfigurability. With the development of micro-nano processing technology, on-chip E-O combs have become a research topic with various applications.

Summary: We demonstrate the first microwave-rate soliton microcomb with high-speed tunability. By integrating an electro-optic modulation element in a lithium niobate microresonator, we achieve a modulation bandwidth of up to 75 MHz and a continuous frequency modulation rate up to 5.0 x 10(14) Hz/s. The device offers a significant bandwidth for locking the repetition rate to an external microwave reference, enabling direct injection locking and feedback locking without external modulation. These features are important for disciplining an optical voltage-controlled oscillator to a long-term reference and have wide applications in frequency combs.

Summary: The self-assembly of particle-like dissipative solitons with mutual interactions highlights the concept of soliton molecules in laser resonators. Controllable manipulation of the molecular patterns through internal motions remains challenging for more efficient tailoring approaches. The phase-tailored quaternary encoding format based on controllable internal assembly of dissipative soliton molecules is reported, showing promising application in high-capacity all-optical storage.

Summary: In this study, the effects of third-order dispersion on microresonator solitons in anomalous dispersion were investigated theoretically and numerically. The temporal position drift of solitons caused by third-order dispersion was observed, and the soliton temporal location stabilization was achieved through pump phase modulation. Furthermore, it was found that the final stable cavity soliton temporal position deviated to the maxima of the pump phase modulation field profile. The research method provides insights into cavity soliton stabilization, on-chip ultrashort pulse formation, and optical information processing.

By stabilizing the repetition rate through injection locking, distance measurements up to 64 mm were demonstrated, with residuals below 2.7 μm compared with a referenced laser interferometer. The proposed system achieved a ranging precision of tens of nanometers and showed potential applications in various fields.

Summary: Temporal Kerr cavity solitons are light pulses that can exist in coherently driven, dispersive resonators with Kerr-type nonlinearity. Previous studies have assumed that the inhomogeneity of the driving field varies slowly across the soliton, leading to linear soliton drift rate. However, in some cases, such as using bichromatic driving or in the presence of third-order dispersion, the assumption of slowly varying inhomogeneity may not hold true.

Summary: This paper reports GaNOI microresonators with intrinsic quality factors over 2.5 million, corresponding to an optical loss of 0.17 dB cm(-1). It demonstrates a parametric oscillation threshold power as low as 6.2 mW and estimates the experimentally extracted nonlinear index of GaN at telecom wavelengths to be n(2) = 1.4 x 10(-18) m(2) W-1, which is several times larger than that of commonly used platforms such as Si3N4, LiNbO3, and AlN. The large intrinsic nonlinear refractive index, together with its broadband transparency window and high refractive index contrast, make GaNOI a promising platform for chip-scale nonlinear applications.

Summary: This study successfully captures the dissipative Kerr solitons generated in a crystalline optical microresonator using the phase-modulation-induced potential gradient technique, and achieves side-mode suppression of the microwave signal through photodetection. The hybrid system simultaneously produces a drift-reduced microcomb and a spectrum-purified optoelectronic oscillator, providing a low-cost solution for microwave and optical metrology.

Summary: Soliton microcombs (SMCs) are spontaneously formed in high-quality microresonators, providing a new tool for on-chip frequency comb applications. The experimental demonstration of a program-controlled single SMC source shows the timely balancing of intracavity thermal effects using an auxiliary laser, leading to deterministic single SMC generation. The proposed SMC source shows improved repetition rate stability and continuous pump frequency tuning.
