Broadband MEMS-based InfraRed spectrometers: The core of a multipurpose spectral sensing photonic platform

Project description

Miniature spectrometers for photonics sensing platforms

Miniature spectrometers are highly required for the identification and quantitative measurement of several chemicals simultaneously. Conventional FTIR spectrometers are bulky benchtop instruments challenged by production cost, ruggedness and size. However, while they can operate up to 25 000 nm, the concept of miniature spectrometers that can reach a wide spectral range coupled with high sensitivity represents a challenge. The EU-funded BROMEDIR project addresses all these challenges by utilising the existing knowledge on miniature spectrometers to develop a new generation of FTIR spectrometers for liquid sensing and PTS spectrometers for gas sensing; these will be demonstrated in sustainable farming, hydrogen supply chain quality monitoring and fuel quality control domains. A cloud-based platform for each application will be developed for data analysis.

Objective

"There is a continuously increasing need for miniaturised sensors providing simultaneous access to multiple chemical and biochemical parameters sensing. Optical spectroscopy is the golden standard for the identification and quantitative measurement of several chemicals simultaneously, using a single device: a spectrometer.
Challenge #1: Conventional FTIR spectrometers are bulky benchtop instruments. Regarding PTS for gas sensing, the proof-of-concept has only recently been validated at macroscopy scale. Considering field deployment of such spectrometers, the main challenges are related to the production cost, ruggedness & size of the instrument.
Challenge #2: A key advantage of FTIR absorption spectroscopy is its broad spectral range in the MIR range, where fundamental molecular vibrational tones have large absorption cross section. However, while conventional benchtop FTIR spectrometers can operate up to 25000 nm or more, it is still a big challenge when considering miniature spectrometers to reach a wide spectral range coupled with high sensitivity.
SIWARE recently developed an ultra-compact, MEMS-based, FTIR spectrometer. The commercial product, NeoSpectra, is operating in the Near-Infrared range up to 2500 nm.
BROMEDIR will address the aforementioned challenges and make an important step towards meeting the related need, using Neospectra as a Spectroscopy Development Platform, targeting though the development of a radically new spectrometer with multiple extensions of its capabilities beyond the SotA. In parallel, a novel, miniaturised PTS spectrometer will be developed, taking advantage of the same silicon-MEMS technology platform that has been used for the development of the PIC used in Neospectra’s FTIR chip. In BROMEDIR, this new generation of miniature spectrometers will be used to develop sensing platforms, to be demonstrated in 3 application domains: a) sustainable farming, b) hydrogen supply chain quality monitoring and c) fuel quality control"
