Abstract
In an example embodiment, an N-channel WDM OSA includes active optical devices coupled to a carrier, an optical block, and a MUX or a DEMUX. The optical block may be positioned above the active optical devices and coupled to the carrier. The optical block may include a bottom with lenses formed in the bottom that are aligned with the active optical devices; a first side that extends up from the bottom; a second side that extends up from the bottom and is opposite the first side; a port that extends forward from the bottom and the first and second sides; and an optical block cavity defined by the bottom and the first and second sides that extends rearward from the port. The MUX or DEMUX may be positioned in the optical block cavity in an optical path between the port of the optical block and the active optical devices.
