MAREŠ, D., et al. Hybrid polymer-glass planar Bragg grating as a temperature and humidity sensor. Optical and Quantum Electronics. 2022, 54(9), ISSN 0306-8919. DOI 10.1007/s11082-022-04003-0.
This paper presents the design and construction of a new planar optical Polymer Waveguide Bragg grating (PWBG) temperature and humidity sensor realized by polymer-glass hybrid technology composition with a new layout concept. The Bragg grating of a sensor was made by a Direct Laser Writing (DLW) in Poly (methyl methacrylate) (PMMA) formed on a multimode waveguide realized in a glass substrate by Ag+ <-> Na+ ion exchange. The fabricated hybrid Bragg grating structure exhibited more than 10 dB of the attenuation dip, equivalent to higher than 90% diffraction efficiency. The fabricated hybrid PWBG sensor exhibited high temperature and humidity sensitivity in contrast to glass-based sensors of - 48.6 pm/degrees C and 54.16 pm center dot RH-1, respectively.
