We demonstrate a double-stage four-wave mixing (FWM) scheme in silicon nanowaveguides which allows effective optical time-division-multiplexed data generation and reception in the 2-μm region. The scheme is based on a first mixing stage which unicas

Optical frequency combs represent a revolutionary technology for high precision spectroscopy due to their narrow linewidths and precise frequency spacing. Generation of such combs in the mid-infrared (IR) spectral region (2-20 um) is of great interes

We report, to the best of our knowledge, the first demonstration of octave-spanning supercontinuum generation (SCG) on a silicon chip, spanning from the telecommunications c-band near 1.5 μm to the mid-infrared region beyond 3.6 μm. The SCG present

We investigate theoretically the parametric frequency comb generation in silicon microresonators at telecom and mid-infrared (MIR) wavelengths in the presence of multiphoton absorption and free-carrier effects using a modified Lugiato-Lefever model.

We demonstrate strong nonlinearities of n2 = 8 t 10-15 cm2 W-1 in single crystal silicon carbide at a wavelength of 2360nm. We use a high confinement SiC waveguide fabricated using a modified smart-cut process.

We demonstrate supercontinuum generation (SCG) spanning from telecom to mid-infrared wavelengths beyond 3.6 μηι, using a silicon-on-insulator wire waveguide, which represents the first octave-spanning SCG from a silicon chip.

We experimentally demonstrate a FWM-based receiver operating at long wavelengths. The scheme successfully demultiplexes a 1866-nm 40-Gb/s NRZ signal into 10-Gb/s tributaries while simultaneously wavelength-converting it to 1320 nm for photodetection.
