Abstract
An oxide-free heteroepitaxial bonding of InP-clad GaInAs quantum wells on Si showing an atomic-plane-thick reconstruction across the InP-Si interface and no degradation of the quantum wells luminescence is demonstrated. Several InP surface preparation procedures have been investigated to ensure an oxide-free bonding. Such a bonding procedure without oxide or metal mediation allows embedding very-high-index-contrast nanostructuration within optic and optoelectronic integrated devices, thus enabling tailored designs enhancing dedicated optical functions. Heteroepitaxial bonding is also similarly obtained on nanopatterned Si surface.
