利用条纹分辨二次谐波相关法,对电吸收调制器产生的光脉冲进行了测量.在不假定光脉冲波形情况下,通过迭代计算,重建光脉冲的波形和位相.在2.5GHz微波调制下测量得到,电吸收调制器产生的光脉冲半极大全宽为30.8ps,波形接近sech2型,频率啁啾约3.8GHz. 相似文献

Conformal mapping techniques are used to obtain the closed-form expressions of the characteristic impedance and effective dielectric constant of the asymmetrical coplanar waveguide with finite line dimensions and substrate thickness. These closed-form expressions are generally applicable to design various particular types of coplanar waveguide transmission lines. 相似文献
