Abstract

Two types of passive integrated optical coupling elements (IOCE) with same functions are proposed and demonstrated on silicon substrate. The elements can be hybridized along with semiconductor laser and coupled to a single intensity modulated optical fiber sensor. The reflective concept of a fiber sensor system is adopted in the designs. The comparison of switching properties of the two devices is made. Preliminary results show that an efficiency (100% back reflected to total signal ratio) of -3.2 dB can be obtained and that back reflected signal intensities lower than 0.34% (-24.7dB) could be observed in on/off-conditions.
