We present broadband on-chip resonators based on SiGe graded-index waveguides
operating in the long-wave infrared spectral range from 7.5 to 9.0 μm wavelength range. A …

Germanium-on-silicon (GOS) represents the leading platform for foundry-based long-wave
infrared photonic integrated circuits (LWIR PICs), due to its CMOS compatibility and absence …

The mid-infrared (mid-IR) wavelength range hosts unique vibrational and rotational
resonances of a broad variety of substances that can be used to unambiguously detect the …

Waveguide integrated optical modulators in the mid-infrared wavelength range are of
significant interest for molecular spectroscopy. This is because on-chip synchronous …

We experimentally demonstrate an all-pass microring resonator (MRR) based on a Y_2O_3
BOX germanium-on-insulator (GeOI) platform operating in the mid-IR region. The ring …
