Novel Photonic Synchronization Approach for Dual Optical Frequency Combs Based on Spread Spectrum Communication
Yaoping Wu, Jincong Hu, Biao Ge, Ningyuan Zhong, Ke Zhang, Hui Yang, Lianshan Yan, Xihua Zou
Southwest Jiaotong University, China
This paper proposes a novel photonic synchronization approach for dual optical frequency combs (OFCs) based on spread spectrum communication. This approach drastically reduces the required large tunable optical delay value through the Vernier effect between the two distinct free spectrum ranges (FSRs) of dual OFCs in the receiver. In experiments, the optical delay value is dramatically proliferated by a factor of 207. This enables a high-efficient synchronization procedure for dual OFCs based on spread spectrum communication or covert communication, reducing the conventionally required maximum optical delay value from 6250 ps to 30.16 ps.

An Approach for Optical Pulse Sequences Achieving (n+1/2) Repetition Rate Multiplication
Ping Li, Kunlin Shao, xiaohu Tang, Zhouyang Pan, Yamei Zhang*, Dan Zhu, Shilong Pan
National Key Laboratory of Microwave Photonics, Nanjing University of Aeronautics and Astronautics, China
An innovative temporal Talbot effect-based technique for optical pulse sequence repetition rate control is presented, capable of achieving arbitrary (n+1/2) multiplication factors. Distinguished from conventional temporal Talbot effect configurations, this approach incorporates a pre-phase modulation process rather than directly employing phase-free optical pulse sequences. The core novelty lies in the straightforward phase manipulation of optical pulses, where carefully designed temporal phase signals allow for precise control of repetition rate through subsequent dispersion. Both numerical simulations and experimental validations have confirmed the effectiveness and feasibility of this method. Experimental demonstrations successfully achieved repetition rate multiplication (RRM) factors of 1/2, 3/2, and 5/2, validating the operational principles and functionality of the proposed technique. The results indicate that this method provides a robust and flexible solution for precise repetition rate control in optical pulse sequences.
