The convergence of microelectronics and photonics on a single chip is one of the greatest challenges of present research. To make it happen, it is necessary to develop an entire novel class of optoelectronic devices exhibiting far beyond the state-of-the-art performance in term of compactness, speed and power efficiency. Silicon photonics enhanced with III-V semiconductors such as InP-based materials is the key technology to provide a platform able with all the necessary functionalities but it is only through the exploitation of nanophotonics concepts that disruptive performance can be reached.
During this presentation, we will show our latest results obtained on electrically powered InP-on-SOI photonic crystal devices. These results will concern first the demonstration of nanolaser diodes emitting at 1.55µm in a SOI waveguide with a wall-plug efficiency higher than 10%. The developed electrical injection scheme allows us, also, to conceive nano-amplifiers and electro-optical modulators which show promising features for their integration in a photonic circuit.
Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for 2018 presentations, with transcripts for prior recordings added daily.
