Fabrication-Tolerant O-Band WDM Filter With Phase-Balanced Tapered Arms and Wavelength-Independent Couplers Open
We design, simulate, and experimentally demonstrate a coarse wavelength-division de-multiplexing system based on cascaded Mach-Zehnder interferometers (MZIs) operating in the O-band. The fabricated devices are built on a monolithic silicon…
