Abstract
In one embodiment, a silicon photonic integrated circuit (PIC) includes a pair of Mach-Zehnder Interferometers (MZI) with a phase shifter to function as a 1×2 optical switches. On one path between the MZIs is a wavelength interleaver. The MZI switch can be controlled to either an all-pass mode or a by-pass mode, therefore setting configurable optical demultiplexing bandwidths to support dual 1.6T FR8/800G FR4 network backward compatibility. The configurable multiplexer operates at set-and-forget mode for the entire operating temperature and the product's lifetime.
