Abstract
Wavelength division multiplexers for space division multiplexing can include wavelength division multiplexing fanout devices or pump-signal combiners for multicore fibers. The disclosure can include wavelength division multiplexers for space division multiplexing (SDM-WDM devices), including wavelength division multiplexing fanout devices and pump-signal combiners for MCFs. The disclosure can include space division multiplexers (SDMs), including adapters between MCFs with different core patterns and/or add-drop multiplexers for MCFs.

A multicore fiber-wavelength division multiplexer (MCF-WDM), comprising:
- a WDM-fanout device comprising a first plurality of longitudinal waveguides, said first plurality of longitudinal waveguides including at least one waveguide configured to propagate light at a first wavelength and at least one waveguide configured to propagate light at a second wavelength, wherein the WDM-fanout device is configured to combine the light at the first wavelength and the light at the second wavelength into a core of a multicore fiber;
- and
- a non-WDM fanout device optically coupled with the WDM-fanout device, the non-WDM fanout device comprising a second plurality of longitudinal waveguides, wherein each waveguide of the second plurality of longitudinal waveguides is configured to not couple light with another waveguide of said second plurality of longitudinal waveguides in the non-WDM fanout device.
An optical coupler array for optical coupling of a plurality of optical fibers carrying light at least at two wavelengths W-1 and W-2 to an optical device, comprising:
- an elongated optical element having a first end operable to optically couple with said plurality of optical fibers and a second end operable to optically couple with said optical device,
- and comprising:
- a common single coupler housing structure;
- a coupling section;
- a plurality of longitudinal waveguides, including at least one first waveguide and at least one second waveguide, each having a capacity for at least one optical mode of a mode field profile, and a corresponding propagation constant, wherein at least one of said plurality of longitudinal waveguides is a vanishing core waveguide,
- wherein, in said coupling section located proximal to said second end, at least one said vanishing core waveguide is in coupling distance to another said longitudinal waveguide, said coupling distance and length of said coupling section are configured to couple light at least at wavelength W-1 of at least one core mode of said at least one said vanishing core waveguide with at least one core mode of another said longitudinal waveguide while continuing the propagation of the light at said wavelength W-2 in said another longitudinal waveguide.
