Abstract
An optical subassembly utilizes a core with a first, second, and third faces. The first and second faces are coupled, non-parallel, and non-co-planar for changing a path of a beam, and their intersection defines an axis. Filters are coupled to the third face. The light path traverses between the first or second face and each filter such that, at each filter, no portion of the light path interferes with any other portion of the light path. The light path also traverses the core in a direction along the axis. This is facilitated by the light path traversing an external surface of a filter at an angle. The device includes adjustable ports residing at the same side of the device. Filters are coupled to the core and optically coupled to the adjustable ports. The light path travels down the core and exit or enter the device via the adjustable ports.
