abstract: The purpose of the work is to develop principles for constructing bulk optical waveguides (BWGs) integrated into porous glass (PG), as the basic components of primary transducers for sensors of the target analyte, to devise methods of the waveguide manufacturing, and to study their properties.To accomplish the purpose, the following tasks have been completed: to experimentally determine the technological mode of local densification of PG matrix using femtosecond laser and fabricate BWGs;to study the optical properties of the BWGs;to develop a primary transducer of a absorption sensor based on the BWG;to develop a primary transducer of a fluorescent sensor based on the BWG in fluorescent indicators pre-impregnated PG;to develop an active BWG with the function of optical signal amplification;to develop a BWG array with a period of 10 µm and its coupling optical system. The main results of the work contain: 1) The existing results on laser processing of PG are reviewed, and a low-peak fluence of <50 J/cm2 is revealed to successfully inscribe BWG in PG; 2) A first type of primary transducer of an absorption sensor is developed and tested. The transducer is formed by a BWG created in the PG, and has a short response time of fewer than 6 seconds; 3) A second type of primary transducer for a fluorescent sensor is manufactured in the form of a BWG created in the PG with rhodamine 6G molecules preliminarily impregnated; 4) A BWGs array with a period of ~ 10 μm and low cross-talk is fabricated, and a coupling optical system is proposed.The main content of the work was published in 8 papers, of which 5 publications in peer-reviewed journals indexed in the VAK, Web of Science or Scopus, 3 publications in Russian Science Citation Index.
