Nonlinear chalcogenide optical fiber couplers

Optics Express, 2022
We demonstrate chalcogenide optical fiber couplers with a power-dependent coupling coefficient. The couplers are designed and fabricated using an As2Se3 fiber and characterized at a wavelength of 1938 nm, leading to a critical power of 126 W, the lowest ever reported for any optical fiber coupler.

Polarization-Insensitive Phase-Transmultiplexing and Multicasting of CSRZ-OOK and 4 $\times$ RZ-BPSK to 4 $\times$ RZ-QPSK via XPM in a Birefringent PCF

IEEE Photonics Journal, 2014
By utilizing cross-phase modulation and birefringence, we demonstrated simultaneous polarization-insensitive phase-transmultiplexing and multicasting of a single 10-Gbaud CSRZ-OOK signal and 4 $\times$ 10-Gbaud RZ-BPSK signals to generate 4 $\times$ 10-
