Abstract Silicon nitride (Si3N4) photonic integrated circuits (PICs) are of great interest due to
their extremely low propagation loss and higher integration capabilities. The number of …

We experimentally demonstrate supercontinuum (SC) generation in a germanium-on-silicon
waveguide. This waveguide exhibits propagation loss between 1.2 dB/cm and 1.35 dB/cm in …

We study the mid-IR optical properties of Sb_2S_3–a phase-change material (PCM) with
high potential for mid-IR integrated photonics. We show that Sb_2S_3 exhibits a high …

Frequency conversion in nonlinear materials is an extremely useful solution to the
generation of new optical frequencies. Often, it is the only viable solution to realize light …

We present three designs of flexible metamaterial nanograting (FMN) with multiple layers.
FMN devices are composed of one, three, and five graphite layers sandwiched by lithium …

On-chip devices for absorption spectroscopy and Raman spectroscopy have been
developing rapidly in the last few years, triggered by the growing availability of compact and …

We experimentally demonstrate the generation of a short-wave infrared supercontinuum in
an uncladded silicon nitride (Si_3N_4) waveguide with extreme polarization sensitivity at the …

On-chip mid-infrared (MIR) supercontinuum generation (SCG) covering the molecular
functional spectral region (3–12 μm) offers the advantages of robustness, simplicity, and …

We report the experimental generation of a broadband and flat mid-infrared supercontinuum
in a silicon-germanium-on-silicon two-stage waveguide. Our particular design combines a …
