A wavelength-division multiplexing (WDM) optical assembly with multiple collimator sets is disclosed herein. The WDM optical assembly includes a WDM optical core subassembly including at least one optical signal router, at least one WDM filter, and a first and second WDM collimator sets. The first WDM collimator set includes a first common optical collimator and at least two channel collimators and the second WDM collimator set includes a second common optical collimator and at least two channel collimators. At least a portion of the first WDM collimator set is optically positioned on a first surface of at least one substrate, and at least a portion of the second WDM collimator set is optically positioned on a second surface of the at least one substrate opposite the first surface. The WDM optical core subassembly increases lane density while decreasing size and minimizing complexity by using a plurality of WDM common ports.

Wavelength-division multiplexing optical assembly with multiple collimator sets

The micro-optical systems disclosed herein employ a glass tube having a body, a front end, a back end, an outer surface, and a bore that runs through the body between the front and back ends and that has a bore axis. The outer surface has a maximum outer dimension between 0.1 mm and 20 mm and includes at least one flat side. At least one optical element is inserted into and operably disposed and secured within the bore. The micro-optical assemblies are formed by securing one or more micro-optical systems to a substrate at the flat side of the glass tube. The glass tube is formed by a drawing process that allows for the dimensions of the glass tube to be small and formed with relatively high precision. An example of a compact WDM micro-optical assembly that employs micro-collimators is disclosed.
