Abstract
Hybrid silicon lasers and amplifiers having resonator cavities within a silicon substrate and a two-dimensional material film on the substrate as an optical gain medium are described. The two-dimensional material film may be formed of one or more atomic layers of phosphorene (BP). The number of phosphorene layers may be adjusted to tune the emission wavelength of the hybrid devices.
Claims15
A photonic device comprising:
- a substrate formed of a semiconductor material, the substrate having a resonator cavity formed therein, the substrate having a mounting surface;
- and
- a two dimensional material disposed on the mounting surface of the substrate and extending over the resonator cavity, the two dimensional material being formed of one or more atomic layers of phosphorene, wherein the two dimensional material is configured to provide a photonic gain region for photons propagating in the resonator cavity of the substrate, such that upon external pumping the two dimensional material produces a photon emission.
A hybrid amplifier comprising:
- a semiconductor substrate having a resonator cavity;
- a two dimensional material disposed on a mounting surface of the semiconductor substrate and extending over the resonator cavity, the two dimensional material being formed of one or more atomic layers of phosphorene, wherein the two dimensional material is configured to provide a photonic gain region for photons propagating in the resonator cavity of the substrate;
- and
- an electrode configuration having at least one electrode disposed at the two dimensional material to pump current into the two dimensional material for conversion into photons for propagation in the resonator cavity, the two dimensional material to produce a photon emission of the hybrid amplifier in response to an external current source supplying the pump current to the electrode configuration.
