We demonstrate integrated distributed Bragg reflector lasers on a hybrid platform composed of silicon nitride waveguides coated with erbium-doped tellurium dioxide. The asymmetrical laser cavities are enclosed by gratings patterned on the 2.2-cm-long waveguide walls. Cavities with varying grating strengths are studied, yielding laser efficiencies up to 0.36%, a minimum lasing threshold of 13 mW, and emission wavelengths between 1530 and 1565 nm.
We describe a prototyping process for silicon nitride photonic integrated circuits, targeting applications in the visible and near-infrared wavelength ranges. The platform is based on direct-write electron beam lithography technology and provides a route toward the rapid fabrication of passive and thermo-optic active photonic devices. The fabrication turnaround time is on the order of several weeks, and critical feature sizes are demonstrated down to 100 nm which enables the fabrication of subwavelength metastructures. Two waveguiding material thicknesses have been demonstrated, 150 nm for visible light applications and 400 nm for infrared.
We present on recent progress on a hybrid tellurite glass and silicon nitride photonic platform. We show low loss waveguides and Q factors < 10^6 in microring resonators. We also show rare-earth-doped active devices, including erbium-doped and thulium-doped waveguide amplifiers and thulium-doped microring lasers. Using the same approach, we demonstrate nonlinear functionalities including efficient four-wave-mixing, supercontinuum generation and third harmonic generation in compact microring resonators and waveguides. The platform is highly promising for compact and low-cost passive, active and nonlinear photonic integrated circuits for applications in computing, communications, sensing and metrology.
