Low-Loss and Low-Crosstalk Fan-in/Fan-out Device for Multicore Fiber Using a Femtosecond Laser Direct Inscription Technique

We demonstrate a low-loss and low-crosstalk fan-in/fan-out device for three-core fiber using femtosecond laser direct inscription. The fabricated FI/FO device has an averaged insertion loss of 1.33 dB and a crosstalk smaller than −49 dB.
