Biophotonic sensors with integrated Si₃N₄-organic hybrid (SiNOH) lasers for point-of-care diagnostics.

ABSTRACT: Early and efficient disease diagnosis with low-cost point-of-care devices is gaining importance for personalized medicine and public health protection. Within this context, waveguide-(WG)-based optical biosensors on the silicon-nitride (Si₃N₄) platform represent a particularly promising option, offering highly sensitive detection of indicative biomarkers in multiplexed sensor arrays operated by light in the visible-wavelength range. However, while passive Si₃N₄-based photonic circuits lend themselves to highly scalable mass production, the integration of low-cost light sources remains a challenge. In this paper, we demonstrate optical biosensors that combine Si₃N₄ sensor circuits with hybrid on-chip organic lasers. These Si<
