中文摘要： 高速率多波长短脉冲光源是未来WDM及WDM-PON光网络中的关键器件。使用单个多波长短脉冲光源可取代WDM技术中数以百计的独立光源器件，从而大幅降低系统成本。多波长短脉冲源在高超快光信息处理以及微波光子学等领域也有广泛应用。传统的多波长短脉冲方案中普遍使用分立光学元件，导致系统成本高昂、体积庞大。本项目基于InP基半导体光子集成芯片技术，准备开展新型高速率多波长短脉冲光源的研究，通过集成技术大幅度降低多波长脉冲源的器件成本和体积，并提高系统可靠性。计划通过相关实验与模拟深入研究与其设计相关的若干科学问题：多波长信道间的模式分配噪声问题；饱和吸收区在多波长光脉冲注入下的时域载流子动态机制及短脉冲整形机理；电混合锁模及光注入锁模状态下脉冲输出的稳定性和定时抖动问题；多波长光信号时钟恢复机理；有源-无源波导集成界面对锁模稳定的影响等。此芯片集成方案在国内外文献中尚无报道，具有较高原创性。

英文摘要： High repetitive rate multiwavelength short pulse light source is a key enabling technology in future WDM and WDM-PON photonic networks, where it can replace the hundreds of discrete lasers individually addressing each WDM channels, resulting in significant cost savings. It also has broad applications in diverse fields such as high speed optical sampling, ultrafast optical processing, and microwave photonics. Traditional approaches for generating multiwavelength short pulse light sources however all require expensive and bulky optical systems with discrete components. We propose a novel monolithically integrated multiwavelenth semiconductor mode locked laser chip in the InP material. Photonic Integrated circuit (PIC) integrating multiple photonic components monolithically onto the same chip is an important technology tend in recent years. By creating system on chip solutions it can dramatically reduce system cost, footprint, improve reliability and expand system functionalities. Critical scientific problems we plan to investigate in depth include mode partition noise effect between wavelength channels, pulse shaping carrier dynamics inside electro-absorptive modulator (EA) under multiwavelength pulse injection conditions, timing jitter stability under electrical hybrid mode locking and optical injection locking,
