Device and method for optical add/drop multiplexing |
摘要 |
An optical add/drop multiplexing (OADM) device includes two MMI structures connected by a MI/MZI waveguide structure comprising a wavelength selector that includes phase shifted Bragg gratings. The OADM multiplexer transmits a wavelength channel selected in advance and reflects all other channels to achieve a drop functionality. Simultaneously, a further channel may be added to the multiplexer at the same side as the channel selected in advance is output. The further channel preferably is centered around the same wavelength as the channel selected in advance. The further channel is transmitted through the Bragg gratings and is superimposed with the other channels to achieve an add functionality. |
