Claim 11:
12. A method of manufacturing a laser-based sensor system-on-a chip for real-time monitoring of a constituent concentration level in a subject, the method comprising the steps of:
manufacturing a tunable hybrid III-V/IV laser sensor by
manufacturing a III-V semiconductor gain-chip,
fabricating a photonic integrated circuit on a group IV-based semiconductor substrate by CMOS technology to define a group IV semiconductor chip, and
hybridly integrating the III-V gain-chip and the group IV semiconductor chip,
wherein the photonic integrated circuit is (i) configured to perform wavelength filtering and tuning functions based on Vernier effect and (ii) defines an external cavity for the III-V gain-chip; and
coupling a fiber-optic interface to the laser sensor, the interface comprising a probe,
wherein during use the laser sensor is remote from the subject and the probe is in optical communication with the subject.
