Abstract

A thermally fixed photorefractive Bragg grating is written in a single-mode Ti:Fe:Er:LiNbO3 channel waveguide and used to develop a distributed feedback-distributed Bragg reflector coupled cavity laser with a second broadband dielectric cavity mirror. The optically pumped (lambda(p) = 1480 nm, P = 130 mW) laser emits in single-frequency operation as much as 8 mW at lambda = 1557.2 nm with a slope efficiency of approximately 22%. The laser wavelength can be thermo-optically and electro-optically tuned over 100 pm.

摘要

一个热固定光折变布拉格光栅写入单模Ti:Fe:Er:LiNbO₃通道波导中，并用于开发一种带有第二个宽带介质腔镜的分布反馈 - 分布布拉格反射器耦合腔激光器。光泵浦（λₚ = 1480 nm，P = 130 mW）激光器在单频工作模式下，在λ = 1557.2 nm处发射功率高达8 mW，斜率效率约为22%。激光波长可通过热光和电光方式在100 pm范围内调谐。
