英文摘要： Multi-wavelength optical pulse generation is a key technology in future ultra-high capacity and high speed fiber-optic network. The technology can be used in the core and access networks based on WDM and OTDM system, optical signal processing and microwave photonics applications. Monolithic integrated multiwavelength semiconductor mode locked laser based on InP material offers many advantages such as smaller size, lower power consumption and lower cost. In this proposal, we propose two monolithically integrated multiwavelength semiconductor mode locked lasers based on arrayed waveguide grating(AWG) and distributed brag reflector(DBR). The research will be focus on design and fabrication issues for multiwavelength semiconductor mode-locked lasers, such as the integration method for materials with two or three different bandgap wavelength, the dependence of mode locking performance on the choice of laser structure, doping level and working condition etc. A multiwavelength mode locked laser prototype will be developed at the end of the program and their application in the fiber-optic system will be investigated.
