Silicon waveguides are now widely used to guide radiation in the near-infrared, mainly in
the wavelength range of 1.1–2.2 µm. While low-loss waveguides at longer wavelengths in …

Silicon-on-insulator (SOI) has been used as a platform for near-infrared photonic devices for
more than twenty years. Longer wavelengths, however, may be problematic for SOI due to …

We have investigated the nonlinear optical response of low loss Si_0. 6Ge_0. 4/Si
waveguides in the mid-infrared wavelength range from 3.25-4.75 μm using picosecond …

We demonstrate electrooptic modulation at a wavelength of 2165nm, using a free-carrier
injection-based silicon Mach-Zehnder modulator. The modulator has a V_π∙ L figure of merit …

We demonstrate low loss ridge waveguides and the first ring resonators for the mid-infrared,
for wavelengths ranging from 5.4 to 5.6 μ m⁠. Structures were fabricated using electron …
