Abstract: A minimally invasive spectrophotometric system. In some embodiments, the system includes a minimally invasive device and a spectrophotometer. The spectrophotometer may include: a transmitting fiber, a receiving fiber, and a head. The head of the spectrophotometer may include: a light source connected to the transmitting fiber and a photodetector connected to the receiving fiber. A portion of the transmitting fiber may be in an insertion tube of the minimally invasive device, and a portion of the receiving fiber may be in the insertion tube of the minimally invasive device. The head of the spectrophotometer may occupy a volume of less than 300 cubic centimeters.

Abstract: An optical sensing module suitable for a gas phase sample, the optical sensing module comprising: a silicon or silicon nitride transmitter photonic integrated circuit (PIC), the transmitter PIC comprising: one or more lasers, each laser of the one or more lasers operating at a wavelength that is different from the wavelength of the others; one or more optical outputs for light originating from the one or more lasers, the optical output arranged such that the light interacts with the gas-phase sample; and one or more photodetectors configured to detect light after interaction with the gas-phase sample.
