Integrated Optical Filter Using Spiral-Based Cascaded Mach–Zehnder Interferometers

Integrated Optical Filter Using Spiral-Based Cascaded Mach–Zehnder Interferometers

We have proposed a new compact integrated optical filter based on cascaded Mach-Zehnder interferometers (MZIs), and designed corresponding coupling structures without S-bend. The wavelength dependence and fabrication tolerance of coupling structures constructed in straight waveguides and bent wavegu...
