INTEC Department and Center for Nano- and Biophotonics, Roel Baets is at the Photonics Research Group, Ghent University-IMEC, B-9000 Gent, Belgium, The Si 3 N 4 PIC (blue) fully cladded with SiO 2 was. An optical isolator is a device used to suppress or redirect backscattered or backreflected light. It is primarily used to isolate the ports from unwanted optical reflections. Our integrated optical isolator consists of three AlN piezoelectric actuators on top of a Si 3 N 4 microring resonator, as shown in Fig. ![]() Wolfgang Freude is at the Institute of Photonics and Quantum Electronics and Institute of Microstructure Technology, Karlsruhe Institute of Technology, 76131 Karlsruhe, Germany,ĭepartment of Electrical Engineering, Shanhui Fan and Zongfu Yu are at Ginzton Laboratory, Stanford University, Stanford, California 94305, USA, An optical isolator is a passive optical device designed to transmit optical signals in only one direction. These devices can handle powers rang from 300mW to 150W or other on request, and have center operating wavelengths ranging from 500nm to 2100nm.
