摘要

本文报道了1.3 μ m InGaAsP单侧增反射涂层激光器在外接光栅强反馈作用下，当光栅中心反射波长从单个激光二极管纵向模式连续调谐到相邻的低频模式时的光谱特性。结果表明，涂层表面不同的残余反射率对激光器内腔模式间调谐特性的影响与理论一致。解释了调谐特性的双稳性。从理论上解释了单模振荡的稳定性和线宽与孤模失谐的关系。

Intermode tuning characteristics of an InGaAsP laser with optical feedback from an external grating reflector

The spectral characteristics are reported of one-side antireflection coated 1.3 mu m InGaAsP lasers exposed to strong feedback from an external grating, when the center wavelength of reflection of the grating is tuned continuously from one solitary laser diode longitudinal mode to the adjacent lower frequency mode. The effects of different residual reflectivities of the coated facet on the tuning characteristics of the laser between internal cavity modes are shown to agree with theory. Bistability in the tuning characteristic is explained. A dependence of the stability of single-mode oscillation and of the linewidth on the detuning from the solitary laser modes is theoretically explained.<>
