Systems And Methods For Providing A Three-Port Reconfigurable Optical Add-Drop Multiplexer With An Improved Edge Profile And Add/Drop Flexibility

摘要

The technology described herein provides a low-cost three-port reconfigurable optical add-drop multiplexer (ROADM) with an improved edge profile and add/drop flexibility. The technology described herein further provides a tunable spectral filter utilizing two sets of gratings and lenses and a two-axis micro-electro-mechanical system (MEMS) mirror with a selectively shaped cut-out disposed within the middle of the collimated optical path.
