Abstract In this work, we demonstrate a full photonic integrated device for performing highly-sensitive biosensing using silicon nitride ring resonators propagating transverse-magnetic modes at wavelengths around 1310 nm. The device includes fully-etched grating couplers as interfaces with external optical fibres. Sensing experiments are performed in a microfluidic environment using bovine serum albumin and anti-bovine serum albumin as biological agents. In comparison with other photonic platforms based on ring resonators propagating transverse-electric modes, our device shows a better detection performance though the efficiency of the grating couplers can be further improved.
