Abstract
A multiplexer/demultiplexer for at least two wavelengths in O-band. The multiplexer/demultiplexer includes a silicon waveguide block having a first port, a second/third port respectively in bar/cross position at an opposing end plane relative to the first port. The silicon waveguide block is configured to provide a general interference excitation of a light wave of a first wavelength and a second wavelength respectively selected from two windows in O-band. The light wave is either inputted via the first port and split into a first output light of the first wavelength out of the second port and a second output light of the second wavelength out of the third port, or is combined of a first input light of the first wavelength from the second port and a second input light of the second wavelength from the third port and outputted via the first port with both wavelengths.
