Abstract
High speed optoelectronic devices and associated methods are provided. In one aspect, for example, a high speed optoelectronic device can include a silicon material having an incident light surface, a first doped region and a second doped region forming a semiconductive junction in the silicon material, and a textured region coupled to the silicon material and positioned to interact with electromagnetic radiation. The optoelectronic device has a response time of from about 1 picosecond to about 5 nanoseconds and a responsivity of greater than or equal to about 0.4 A/W for electromagnetic radiation having at least one wavelength from about 800 nm to about 1200 nm.

Documents recorded with the USPTO Assignment Recordation Branch that list this patent. A security interest is a lender’s claim on the patent as collateral; a release ends it.
USPTO bulk data: PatentsView granted patents, disambiguated (PVGPATDIS) for patents, assignees, inventors, places and CPC categories; the USPTO Patent Assignment Dataset (ECORSEXC) for assignments and security interests. Patents filed in the last 20 years. No claims or full text. Links to other records are by name (and state): EXACT means the identical full name and state; FUZZY means a looser name match, with the confidence shown.
