摘要
本文报道一种具有两组电极、与偏振无关的M-Z型波导调制器,它具有两组驱动电压都较低而且数值相近的特点。在波长λ=0.633μm下测试,两组电压分别为11V和15V,消光比大于95％,理论带宽1.21GHz。
An interferometric waveguide modulator independent of polarization is reported, which has two sets of electrodes with low and approximately equal drive voltages. The driving voltages of TE-and TM-mode at 0.633μm are about 15and 11V respectively, with an extinction ratio of above 95% and estimated bandwidth of 1.21 GHz.
