英文摘要： Low cost and high response optical receiver has great application in optical communication network. Broadband pumped Eu-Er waveguide amplifier with several advantages such as low noise, high gain, low cost and easy integration is ideal choice for high response optical receiver and important device for future chip optical interconnection. For the need of high response optical receiver, this project aims to study novel high gain Europium-Erbium waveguide amplifier. By virtue of the number of optical active Er3+ in rare earth silicatel can exceed 1021cm-3,the project will introduce the high concentration Eu2+ and Er3+ in silicate lattice and analyze the dynamic energy transfer processes from the sensitized Eu2+ centers to activated Er3+ centers, and elucidate their related mechanism. Through optimizing the silicate crystalline structure and rare earth concentration, the new Erbium compound films with highly luminescence efficency under broadband excitation will be designed and prepared. To improve the top pump efficiency, the resonant cavity enhanced structure will be designed. By optimizing the waveguide structure and preparation technology, the high performance Erbium waveguide amplifier will be fabricated.
