The first results of distributed optical fiber radiation sensing measurements based on radiation induced attenuation (RIA) at the new mixed-field irradiation facility CHARM are presented.
We report on multiple resonant cavities coupled to a single photonic crystal waveguide operating as a multi-channel sensor. This device is characterized by as many dips in its transmission spectrum as there are cavities. Good reproducibility is observed between the spectrum of double-channel device and those of the single cavities. Infiltration of isopropanol in the holes leads to a red shift of the...
Porous silicon is widely studied in the field of photonics due to its interesting optical properties. In this work, we present theoretical and first experimental studies of a new kind of porous silicon photonic device based on optical surface wave. A theoretical analysis of the device is presented using plane-wave approximation. The porous silicon multilayered structures are realized using electrochemical...
