Abstract
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.
Claims14
A method of performing optical amplification of a light signal on a silicon platform comprising:
- positioning a first doped device layer;
- positioning a second doped device layer;
- and
- exposing said light signal to a gain medium positioned between said first and second doped device layers, said gain medium comprising extrinsic gain materials so as to substantially confine in said gain medium said light signal and allow said optical amplifier to be electrically and optically pumped, said gain medium having a linear output coupling slot waveguide configuration that allows for substantial confinement of an optical field within said gain medium when suitable polarization of said optical field propagating in said linear output coupling slot waveguide has a magnetic field predominantly polarized in a plane parallel to a plurality of interfaces of said linear output coupling slot waveguide, said linear output coupling slot waveguide allows electrical current to be transported through said gain medium.
