An optical device that can be configured to multiple different optical components. In one embodiment, the optical device can be configured to operate as a single double-pass interlayer/deinterleaver, as two single-pass interleaver/deinterleavers, or as one or more filters. In one embodiment, the optical device has ports on two or more planes and a birefringent element that occupies the two or more planes. Connections between the two or more planes can be made by walk-off crystals internal to the optical device or between ports by connections that are external to the optical device to configure the optical device.
