An optical amplifier on a silicon platform includes a first doped device layer and a second doped device layer. A gain medium is positioned between the first and second doped device layers. The gain medium comprises extrinsic gain materials so as to substantially confine in the gain medium a light signal and allow the optical amplifier to be electrically or optically pumped.

Electrically pumped extrinsic semiconductor optical amplifier with slot waveguide

A process for forming a porous nanoscale membrane is described. The process involves applying a nanoscale film to one side of a substrate, where the nanoscale film includes a semiconductor material; masking an opposite side of the substrate; etching the substrate, beginning from the masked opposite side of the substrate and continuing until a passage is formed through the substrate, thereby exposing the film on both sides thereof to form a membrane; and then simultaneously forming a plurality of randomly spaced pores in the membrane. The resulting porous nanoscale membranes, characterized by substantially smooth surfaces, high pore densities, and high aspect ratio dimensions, can be used in filtration devices, microfluidic devices, fuel cell membranes, and as electron microscopy substrates.

A method of making an energy conversion device includes forming a plurality of pores within a substrate and forming a junction region within each of the plurality of pores. Each of the junction regions has a depletion region and each of the plurality of pores defines an opening size in the substrate and a spacing from adjacent pores so that the depletion regions of each of the pores is at least substantially in contact with the depletion region of the pores which are adjacent.

Methods of making energy conversion devices with a substantially contiguous depletion regions
