在这篇文章中，我们报道了一种由硅波导和EO聚合物包层组成的电光调制器。在混合波导中，TE0模式高度局限于硅芯周围。因此，我们得到了相对较小的半波电压长度积（Vπ l）为2.15 V·cm。测量得到的VπL比标准聚合物波导调制器的值小28%。此外，混合结构在移相器部分的传输损耗为0.46 dB/mm。
In this letter, we report an electro-optic (EO) modulator consisted of the silicon waveguide with the EO polymer cladding. In the hybrid waveguide the TE0 mode is highly confined around the silicon core. Thus, we obtained relatively small half-wave-voltage length product (VπL) of 2.15 V·cm. The measured VπL is 28% smaller than the value obtained from standard polymer waveguide modulator. In addition, the hybrid structure possesses a propagation loss of 0.46 dB/mm in phase shifter part.
