摘要

在氟化锂晶体中注入不同剂量的2 MeV He/sup +/离子，制备了平面有源波导，并用光学吸收、光致发光和m线光谱对其进行了表征。所有的有色样品都支持几种模式，其分析可以重建作为剂量函数的波导的深度折射率分布。两种相互竞争的物理机制，与离子轨道上不同的能量沉积过程有关，负责辐照体积中折射率的正修正和负修正。

Optical characterization of active waveguides produced in lithium fluoride by He/sup +/ implantation

Planar active waveguides, produced in lithium fluoride crystals by implantation with 2 MeV He/sup +/ ions at several doses, have been characterized by optical absorption, photoluminescence and m-lines spectroscopy. All the colored samples support several modes, whose analysis allows reconstruction of the depth refractive index profiles of the waveguides as a function of dose. Two competitive physical mechanisms, associated with different processes of energy deposition along the ion track, are responsible for positive and negative modifications of the refractive index in the irradiated volume.
