“…Extensive work has been undertaken to combine active materials with Si 3 N 4 waveguide wafers by adding additional materials such as III-V semiconductors [18], which require epitaxy or bonding of III-V materials to a silicon nitride waveguide wafer. In another example colloidal quantum dots were used for an optically pumped laser by embedding them in a Si 3 N 4 disc raised on a Si pillar [19], which required a rather elaborate fabrication. Both approaches could be, in principle, used for integrated light sources, however complexity of fabrication would limit the industrial relevance due to high costs.…”

Metal-halide perovskites are a class of solution processed materials with remarkable optoelectronic properties such as high photoluminescence quantum yields and long carrier lifetimes, which makes them promising for a wide range of efficient photonic devices. In this work, we demonstrate the first successful integration of a perovskite laser onto a silicon nitride photonic chip. High throughput, low cost optical lithography is used, followed by indirect structuring of the perovskite waveguide. We embed methylammonium lead tri-iodide (MAPbI) in a pre-patterned race-track microresonator and couple the emitted light to an integrated photonic waveguide. We clearly observe the build-up of spectrally narrow lasing modes at room temperature upon a pump threshold fluence of 19.6 µJcm. Our results evidence the possibility of on-chip lasers based on metal-halide perovskites with industry relevance on a commercially available dielectric photonic platform, which is a step forward towards low-cost integrated photonic devices.

“…In our study, we have developed a fully inorganic and low-loss Si 3 N 4 -QD hybrid photonic platform by using a low-temperature (120°C-270°C) plasma enhanced chemical vapor deposition process and an optimized dry etching step, and demonstrated loss as low as 2.7 dB∕cm at 900 nm wavelength for waveguides with embedded QDs [49]. [50]. A spectrum for a disk of radius 3.5 μm is shown in Fig.…”

There is a rapidly growing demand to use silicon and silicon nitride (Si 3 N 4 ) integrated photonics for sensing applications, ranging from refractive index to spectroscopic sensing. By making use of advanced CMOS technology, complex miniaturized circuits can be easily realized on a large scale and at a low cost covering visible to mid-IR wavelengths. In this paper we present our recent work on the development of silicon and Si 3 N 4 -based photonic integrated circuits for various spectroscopic sensing applications. We report our findings on waveguide-based absorption, and Raman and surface enhanced Raman spectroscopy. Finally we report on-chip spectrometers and on-chip broadband light sources covering very near-IR to mid-IR wavelengths to realize fully integrated spectroscopic systems on a chip.
