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.
