Results in brief
Single-Chip Integration of MEMS Micropumps with Optical Waveguides for Laser Absorption Spectroscopy
Sensitive gas spectroscopy is typically performed at sub-atmospheric pressure to enhance absorption line resolution, enabling precise detection and analysis of gas compositions. The primary objective of this project is to develop a miniature system capable of reducing pressure within a microlitre-volume chamber, seamlessly integrated with a midinfrared nanophotonic gas detection unit for high-precision gas sensing. During the project, the focus partially shifted towards the development of a more versatile spectrometer based on a programmable photonic integrated circuit (PIC). At the time of its conception, this PIC represented a unique technological advancement, leveraging the specialized expertise of the project collaborators. This innovative device offers adaptability for multiple applications, including wavelength multiplexing for data transfer, Raman spectra analysis, and gas absorption spectra analysis, thereby broadening the scope and impact of the original objectives.

Project objective
Microbiological research is concerned with studies of microbial gas consumption and production, which is tightly linked to natural greenhouse gas emissions, but also sinks. Currently, such studies require large and expensive instrumentation like gas chromatography systems, which also sacrifice the sample during each measurement. This affects the conditions of the sample, and yields unsatisfactory temporal resolution due to the need for sample handling. In this project, I propose to leverage the latest advances in MEMS and nanophotonics to develop the first chip platform integrating optical waveguides with micropumps, which will facilitate tuneable diode laser absorption spectroscopy (TDLAS) under vacuum and in closed valume without sacrificing the sample gas. With the addition of lasers and light detectors, it will enable inexpensive, low weight, portable devices for real-time, in situ trace gas detection. Such device will not only impact microbiological research, but also sensor networks much needed e.g., in cities for controlling the air quality.
