摘要：
The influence of lateral loss effects on the second-harmonic distortion (SHD) of vertical-cavity surface-emitting lasers is investigated theoretically. Two parameter's, differential confinement factor and differential cavity loss, are defined for the consideration of self-focusing and diffraction loss, It is found that SHD increases at low modulation frequencies due to the presence of differential cavity loss, especially for lasers with small core radius.
