Missions

the postdoctoral fellow will be first in charge of the design of the SiN photonic circuit integrated on SiO2/Si, including gratings couplers enabling either ultrafast laser pulses propagation and emission (central coupler in Fig. 1), or continuous wave directive and polarization independent emission (side couplers in Fig. 1), possibly inspired from [1]. Then he/she will be involved in technological fabrication: micro/nanostructuration of the MO garnet, and photonic circuit realization. Finally he/she will perform the continuous wave characterization of the photonic circuit.
The postdoctoral fellow will be part of the ANR project ULTRAMAG consortium: he will participate to the project meetings and contribute to project results communications and publications.
