Miniaturized in-flight calibration stimulus (uSPEC)
After a series of studies in the framework of PEP and InstrumentCluster SpaceNed partners cosine Remote Sensing, LioniX International and TNO are performing a breadboarding phase (2020 -2022) that will be completed in 2022. In the project a breadboard of a 1550nm calibration system will be realized next to a 850nm laser module, both based on a ultra-narrow linewidth tunable laser platform of LioniX. The proposed miniaturized calibrators integrate a exhibits a power up to ~10 mW, a line-width of tens of picometres and a tunability range in the order of tens of nanometers. Considered application cases are covering the spectral domain between 405 nm and 2385 nm, and they relate to implementation opportunities in a wide range of remote sensing optical instruments, among which HyperScout, Spectrolite and IRSI. Initial performance results of the hybrid-integrated tunable laser have been reported at the Optical Fiber Conference in San Diego on March 10th 2022. In parallel, LioniX International has started an ESA project under the Open Space Innovation Platform (OSIP) to check the radiation hardness of the laser.

ESA-TRP study Integrated label-free detection in optofluidics systems for sample analysis
Initiated by LioniX International and founded on the earlier developed Life Marker Chip prototype in the framework of the EXOMARS mission, Kayser Italia, LioniX and Surfix Diagnostics are performing a study (2020 – 2022) in which a breadboard of a miniaturized sample analysis system will be realized. Based on a broad inventory study, the core of the system is a hybrid integrated photonic chip based biosensor-array, a platform developed by LioniX and to be commercialized by Surfix (COVID-serology test) and Qurin Diagnostics (early cancer detection). In the study the properties of this extremely sensitive detection platform will be characterized on model analytes related to health (ISS application) and life biomarkers (planetary exploration).
