Abstract
A miniature dense wavelength division multiplexer (DWDM) is disclosed. A plurality of multi-window wavelength multiplexers (MWDM) are cascaded and optically coupled to form a tree, and each of the MWMDMs forming the tree comprises a microbend coupler. The forming of the MWDM tree is characterized by the absence of the bending of optical fibers external to the microbend couplers. A finished DWDM assembly measures less than 50 mm in width.
