Abstract: Techniques and mechanisms for a monolithic photonic integrated circuit (PIC) to provide spectrometry functionality. In an embodiment, the PIC comprises a photonic device, a first waveguide and a second waveguide, wherein one of the first waveguide and the second waveguide includes a released portion which is free to move relative to a substrate of the PIC. During a metering cycle to evaluate a material under test, control logic operates an actuator to successively configure a plurality of positions of the released portion relative to the photonic device. In another embodiment, light from the first waveguide is variously diffracted by a grating of the photonic device during the metering cycle, where portions of the light are directed into the second waveguide. Different wavelengths of light diffracted into the second waveguide may be successively detected, for different positions of the released portion, to determine spectrometric measurements over a range of wavelength.

Abstract: Systems and methods may provide for receiving an electrical measurement signal from a first photodetector coupled to a first waveguide and determining a total intensity level of reflected light in the first waveguide based on the electrical measurement signal. Additionally, a perspiration level of skin in contact with the first waveguide may be determined based on the total intensity level of the reflected light in the first waveguide. In one example, an electrical control signal is received from a second photodetector coupled to a second waveguide that is physically isolated from the skin, wherein the total intensity level of the reflected light in the first waveguide is determined further based on the electrical control signal.
