Abstract

A spectrometer may include: a tunable on-chip laser source configured to irradiate a biological tissue with laser radiation; a photodetector configured to receive the laser radiation reflected from the biological tissue; and at least one processor. The tunable on-chip laser source may include: a semiconductor gain chip having a gain bandwidth for operating the tunable on-chip laser source in a predetermined wavelength range; and a plurality of resonator cavities connected between the semiconductor gain chip and the at least one processor, and configured to perform a coarse high-speed measurement and a fine measurement to measure a spectrum of the laser radiation reflected from the biological tissue.
