Ion-slicing
WebHere, we report an efficient and compact waveguide amplifier based on erbium-doped LNOI waveguides, achieved using a sequence of erbium-doped crystal growth, ion slicing, and lithography-based waveguide fabrication. Using a compact 5 mm long waveguide, we demonstrate an on-chip net gain of > 5 d B for 1530 nm signal light with a relatively low ... WebIn this paper, we focus on ion-slicing of 4-inch InP and 2-inch freestanding (fs-) GaN wafers. In the first section, we will demonstrate how epitaxy-compatible InP-on-Si substrates can be achieved. In the second section, we will address different issues involved in the case of 2-inch fs-GaN. Finally, by using a variety of experimental
