Mode-group-selective photonic lantern based on integrated 3D devices fabricated by ultrafast laser inscription

We demonstrate a three-dimensional adiabatically-tapered mode-group-selective space-division multiplexer fabricated by ultrafast laser inscription. The device supports two mode groups at 1550 nm, has a loss of <;4 dB, and is scalable to more modes.
