摘　　要：将纳米技术与光纤技术相结合,利用改进的化学气相沉积法(MCVD)制作纳米级InP薄膜内包层光纤及在普通单模光纤纤芯中掺杂纳米级InP粒子的新型光纤,前者单位长度放大系数最大达到15.35dB/m,能在较短的长度上对信号光起到放大作用,便于集成化;后者经实验证实其纤芯具有光波导传输性能.两种新型高非线性光纤在光通信器件中的具有应用前景.With the combination of the nano-technique and the manufacture of the fiber, the improvement of MCVD is used to develop the inner-cladding fiber with the nano-InP film and the new-style within the core of the normal single fiber doped with the particle of nano-InP. The former fiber has the highest amplificatory coefficient of 15.3 5 dB/m at the unit length, and it has the good amplification performance at the short length which is convenient for integration; the latter fiber has the wave-guide in the core that is proved in the experiment. The development of the fibers above will offer a stable basement of the experiment to get the high nonlinearity fiber.
