摘　　要：稀土掺杂光波导放大器(RDWA)是继光纤放大器(RDFA)之后的新一代稀土掺杂光放大器,其更适用于未来光放大器集成化、小型化的要求,并且在降低成本方面优势明显。提高RDWA性能通常从提高稀土离子发光效率和降低波导损耗两个方面进行探究,这就要求更加合适的掺杂材料和高性能的波导结构,以及尽可能低的传输损耗。总结了稀土掺杂玻璃基、聚合物基、硅基及低损耗材料基质光波导放大器的研究进展,最后展望了本领域的发展前景。With the advantages in integration,miniaturization and economical efficiency,the rare-earth doped waveguide amplifier（RDWA）is developed as an amplifier of new generation.Two feasible ways to optimize RDWA are to improve luminous efficiency of rare-earth doped in the material as well as to reduce the loss of the amplifier.This optimization of RDWA requires more applicable materials,high performance waveguide structure and ultra-low loss materials.This paper reviews glass-based,polymer-based,silicon-based and low-loss material based RDWA,and pictured the prospects of practical applications and possible development of RDWA.
