We review recent demonstration of stimulated Brillouin scattering in a chalcogenide photonic chip and its application to optical and microwave signal processing tasks. The interaction between light and sound via stimulated Brillouin scattering (SBS) was exploited in chalcogenide photonic circuits to achieve on-chip SBS slow and fast light, microwave photonic filters, and dynamic gratings using travelling-wave geometry. Using a ring-resonator geometry, photonic-chip based Brillouin laser was demonstrated.

“…Recently DFB Brillouin lasing has been achieved in silica fiber with a π phase-shifted Bragg grating. 21 Considering chalcogenide waveguides, Bragg gratings can be induced by exploiting photosensitivity of the material to visible light as has been demonstrated earlier by Shokooh-Saremi et al 22 The model for the DFB BL, proposed recently by Winful et al, 23 allows one to estimate the power threshold for on-chip DFB BL and its efficiency. A 1 cm uniform Bragg grating in an As 2 S 3 chalcogenide waveguide is considered as a DFB structure.…”

In recent years, chalcogenide glasses have emerged as a material platform for nonlinear signal processing and mid-infrared photonics. In addition, high Brillouin gain of these soft glasses enable compact and highly efficient Brillouin lasers (BL). We review recent progress on chalcogenide BL, compare fiber and waveguide laser geometries, and discuss the potential of chalcogenide platform for compact and high-coherence light sources.

“…Surprisingly, bandedge effects on stimulated Brillouin scattering (SBS), one of the strongest nonlinear phenomena, have not been experimentally demonstrated to date. A power-efficient way to generate SBS, however, would advance on-chip SBS applications, in particular Brillouin lasers 14 and Brillouin frequency combs 15 .…”

On-chip nonlinear optics is a thriving research field, which creates transformative opportunities for manipulating classical or quantum signals in small-footprint integrated devices. Since the length scales are short, nonlinear interactions need to be enhanced by exploiting materials with large nonlinearity in combination with high-Q resonators or slowlight structures. This, however, often results in simultaneous enhancement of competing nonlinear processes, which limit the efficiency and can cause signal distortion. Here, we exploit the frequency dependence of the optical density-of-states near the edge of a photonic bandgap to selectively enhance or inhibit nonlinear interactions on a chip. We demonstrate this concept for one of the strongest nonlinear effects, stimulated Brillouin scattering using a narrow-band one-dimensional photonic bandgap structure: a Bragg grating. The stimulated Brillouin scattering enhancement enables the generation of a 15-line Brillouin frequency comb. In the inhibition case, we achieve stimulated Brillouin scattering free operation at a power level twice the threshold.
