We demonstrate a compact interrogation method for resonance-based biosensors, based on an integrated photonic chip with an array of resonant-cavity enhanced photodetectors. Due to the high signal-to-noise ratio, wavelength shifts in the 10 pm range can be measured, orders of magnitude smaller than the sensor and interrogator linewidths. This approach allows the read-out of resonance-based optical biosensors with simple integrated components, potentially enabling compact and low-cost sensing systems for point-of-care diagnostics.
