Abstract
A sensor architecture that uses fixed wavelength light and tunes a wavelength dependent response of a sensor may be used for detecting analytes in a wide range of applications. The sensor architecture is based on optical resonators or interferometers comprising optical waveguides. A resonance wavelength and/or transmission/reflection spectrum are affected by presence of an analyte adsorbed on a surface of the waveguide, and a setting of a phase modulator. The sensors include a sensor portion where part of the waveguide is exposed to a sample for sensing, and a phase modulator part. The phase modulator part may include a heater that is controlled to tune, or sweep, or modulate the resonant wavelength and/or spectrum of the sensor.
