- *Introduction to Stimulated Brillouin Scattering (SBS)* : A brief introduction to SBS, a nonlinear interaction between optical photons and acoustic phonons in a photonic waveguide, is provided. The video explains the dispersion diagram and the conditions for forward SBS. - *Fabrication of Freestanding Waveguide on a Photonics Platform* : The video discusses the fabrication of freestanding waveguides on an active silicon photonics platform, IMEC's iSiP50G, with gain and phase modulators. This enables advanced on-chip applications and commercialization. [Watch segment](ruclips.net/video/utJXfmOOwXI/видео.html) - *Design of Brillouin Active Waveguides* : Two different kinds of rib waveguides, FC and SKT, are designed. The waveguides differ in edge depth, and the silicon waveguides are suspended to achieve good acoustic mode confinement. - *Measurement of Stimulated Brillouin Scattering Using Cross-Phase Modulation Scheme* : - The pump is amplitude modulated (carrier and two sidebands) and injected with a weak probe. [Watch segment](ruclips.net/video/utJXfmOOwXI/видео.html) - Cross-phase modulation from the strongly amplified pump leads to modulation of the probe at the output of the waveguides. - A bandpass removes the pump, and a fiber Bragg grating with 2.5GHz bandwidth removes the higher sideband (anti-stokes) from the probe, converting phase modulation into intensity modulation. - A vector network analyzer RF output is fed into an intensity modulator. - Fano resonance is observed from interference of narrow-band SBS and wide-band Kerr nonlinearity. - Each Fano-resonance corresponds to a different mechanical mode in the rib waveguide.
you said the si waveguide on SiN with suspended part is not cmos compatible but finally your waveguide is also suspended strucutre, how this is cmos compatible? you should use the same standard

really interesting how can contact you?
