US Patent 11769989 Long wavelength VCSEL and integrated VCSEL systems on silicon substrates

VCSELs designed to emit light at a characteristic wavelength in a wavelength range of 910-2000 nm and formed on a silicon substrate are provided. Integrated VCSEL systems are also provided that include one or more VCSELs formed on a silicon substrate and one or more electrical, optical, and/or electro-optical components formed and/or mounted onto the silicon substrate. In an integrated VCSEL system, at least one of the one or more electrical, optical, and/or electro-optical components formed and/or mounted onto the silicon substrate is electrically or optically coupled to at least one of the one or more VSCELs on the silicon substrate. Methods for fabricating VCSELs on a silicon substrate and/or fabricating an integrated VCSEL system are also provided.
