In this study, a microfluidic structure was formed on a fluoride fiber by femtosecond laser processing, and a spectroscopy cell suitable for infrared measurements of liquid samples was constructed. Absorption responses corresponding to concentration were confirmed through measurements using glucose aqueous solutions with the fabricated structure. Focusing on the sake brewing process, this technique aims to be applied to infrared spectroscopy for detecting changes in components such as glucose and ethanol, thereby enabling visualization of the fermentation process and contributing to the quantitative control of product quality.
