Summary form only given. In this work we present and discuss our solutions of photonic integrated interrogators for application in a novel fiber-optic sensing system, dedicated to monitoring condition of a patient exposed to magnetic resonance imaging (MRI) scanning procedure. The monitoring system makes use of multiple fiber Bragg grating (FBG) based sensors, which offer the advantages of high sensitivity and immunity to strong magnetic fields and simultaneously do not affect the results of an MRI scan. Furthermore, the fact that many gratings can be inscribed within a single optical fiber simplifies the architecture of the sensing network. Basically, two main approaches to interrogate FBG-based sensors can be distinguished. The first uses a broadband optical signal, which is coupled into the fiber-optic sensing network, while the reflected spectrum is monitored using a spectrometer, typically equipped with a number of detectors. In the second approach a monochromatic, wavelength-swept light is used to scan the sensors and the reflected signal is detected using a single photodetector. The solutions presented and discussed in this work are based on the first approach and make use of generic technology of photonic integration
