Optical modulation in Ge-rich SiGe waveguides in the mid-IR wavelength range up to 11 um
Miguel Montesinos-Ballester, Vladyslav Vakarin, Joan Manel Ramirez +11
Waveguide integrated optical modulators in the mid-infrared (mid-IR) wavelength range are of significant interest for molecular spectroscopy in one hand, as on-chip synchronous det…
Trimming and ultra-wide bandwidth expansion of silicon frequency comb spectra with self-adaptive boundary waveguides
Jianhao Zhang, Vincent Pelgrin, Carlos Alonso-Ramos +3
Dispersion engineering is among the most important steps towards a promising optical frequency comb. We propose a new and general approach to trim frequency combs using a self-adap…
Wideband tunable microwave signal generation in a silicon-based optoelectronic oscillator
Phuong T. Do, Carlos Alonso-Ramos, Xavier Le Roux +3
Si photonics has an immense potential for the development of compact and low-loss opto-electronic oscillators (OEO), with applications in radar and wireless communications. However…
Self-adaptive waveguide boundary for wideband multi-mode four-wave mixing
Jianhao Zhang, Carlos Alonso-Ramos, Laurent Vivien +2
We propose a new approach to provide wideband multi-mode four-wave mixing, independent of the intrinsic waveguide dispersion. We adopt concepts from quantum mechanics and sub-wavel…
