Abstract
Micro-structuration of rare earth doped materials by liftoff processing in pulsed laser deposited layers are promising in photonics since they do not require etching. In this work, we present our recent progress in the fabrication and characterization of such structures for visible and infrared emission. Different kinds of devices have been investigated (micro-disks, micro-strips, grating and so one), with different host materials (Y2O3 and Al2O3) and dopant (Eu3+ and Er3+ ions). We show here that the shape and the material of the microstructures can be chosen to control the light for different wavelength ranges. This work opens the way of the easy realization of efficient micro-emitter for photonics applications.
