Nonlinear Optics in Doped Silica Glass Integrated Waveguide Structures (2008, background): “This result is extremely impressive, and is well above the threshold for silicon (Dulkeith et al., 2006; Liang & Tsang, 2004; Tsang & Liu, 2008), AlGaAs (Siviloglou et al., 2006), or even Chalcogenides (Nguyen et al., 2006).”
All-optical efficient wavelength conversion using silicon photonic wire waveguide (2006, unknown): “In our waveguide, for example, the free-carrier lifetime was measured to be 700 ps, which is about 1/100 of those in conventional rib-type waveguides without reverse bias [5], [16]; therefore, carrier accumulation would be well sup-”
