Abstract
We developed a multiband switch element using a Mach-Zehnder interferometer with π shift utilizing wide and narrow waveguides for large fabrication tolerance. The fabricated 8 × 8 matrix switch using the element exhibited switch extinction ratios of more than 47 dB in wavelength from 1260 to 1675 nm. The average insertion loss was 1.8 dB including fiber coupling losses. © 2022 The Author(s)
