ABSTRACT We report the first observation of Stimulated Raman Scattering (SRS) in silicon waveguides. Amplification of the Stokes signal, at 1542.3 nm, of up to 0.25 dB has been observed in Silicon-on-Insulator (SOI) waveguides, using a 1427 nm pump laser with a CW power of 1.6 W, measured before the waveguide. Two-Photon-Absorption (TPA) measurements on these waveguides are also reported, and found to be negligible at the pump power where SRS was observed.

    ABSTRACT: A one-dimensional sub-wavelength silicon grating with enhanced Raman response is demonstrated. Furthermore, the polarization response of the Raman is investigated. This study shows that, contrary to intuitive expectation, the Raman intensity can be similar for both input polarizations: parallel and perpendicular to the ruling direction. This similarity is achieved due to inter-ridge coupling and polarization dependent characteristics of the grating. Through optimization of the ridge width and spacing, enhanced Raman intensity is realized in both polarizations, simultaneously. The results are further understood using a finite difference time domain model based on the light interaction with the grating for each polarization.

    ABSTRACT: Stimulated Raman scattering in silicon-rich silicon oxide (SiOx, x < 2) films annealed at 1200 °C is measured with excitation at 785 nm. Our main objective is to confirm giant Raman gain, recently reported in annealed SiOx films for excitation at ∼1500 nm. Another important aspect is the possibility of using SiOx films for the realization of a Raman laser in the visible region. The measurements were performed in the backscattering geometry in a Raman microscope. As a result, the observed Raman gain is orders of magnitude greater than in crystalline silicon.
