标题： Low-dispersion low free-spectral-range Mach-Zehnder interferometer with long straight path lengths on silicon

摘要： 使用光纤布拉格光栅耦合器、Y型分支、硅波导和/或硅绝缘体上条形波导中的宽带分束器构建多个马赫-曾德尔干涉仪，以测试连续弯曲之间波导长度变化对传输增益谱、自由光谱范围、群折射率和色散的影响。 通过增加最小半径连续弯曲之间的路径长度来减轻色散。 在长直线波导段的情况下，实现了 0.41 nm 的自由光谱范围。 显示英文摘要

摘要： Multiple Mach-Zehnder interferometers are constructed using fiber-Bragg grating couplers, y-branches, silicon waveguides, and/or broadband splitters in silicon on insulator strip waveguides to test the effect of variation in waveguide length between consecutive bends on the transmission gain spectrum, free-spectral range, group refractive index, and dispersion. Dispersion is mitigated by increasing the path length between consecutive bends of minimum radius. With long linear waveguide sections, a free spectral range of 0.41 nm is achieved.
