用点匹配法计算了与偏振无关调制器的半波电压,用FFT-BPM法分析两平行波导之间的耦合,设计制作了在1.3μm波长下工作的与偏振无关调制器
The half-wave voltage of polarization-independent modulator is calculated by point matching method. The coupling between two parallel waveguides is analyzed by FFT-BPM method. The polarization-independent modulator working at 1.3 μm wavelength is designed
