10 Gb/s InP-based Mach-Zehnder modulator for operation at 2 μm wavelengths

Si-rich Si nitride waveguides for optical transmissions and toward wavelength conversion around 2 μm

We show that subwavelength Si-rich nitride waveguides efficiently sustain high-speed transmissions at 2 μm. We report the transmission of a 10 Gbit/s signal over 3.5 cm with negligible power penalty. Parametric conversion in the pulsed pump regime is also demonstrated using the same waveguide structure with an efficiency as high as -18  dB.

Demonstration of High-Speed Optical Transmission at 2 µm in Titanium Dioxide Waveguides

We demonstrate the transmission of a 10-Gbit/s optical data signal in the 2 µm waveband into titanium dioxide waveguides. Error-free transmissions have been experimentally achieved taking advantage of a 23-dB insertion loss fiber-to-fiber grating-based injection test-bed platform.
