| 摘要 |
A system for use as an optical switch is disclosed. The system includes light emitting devices formed using high quality epitaxial layers of compound semiconductor materials overlying an accommodating buffer layer on a silicon wafer. The system also includes a tunable electro-optic substrate over the compound semiconductor material, and a polarization beam splitter over the electro-optic substrate. The tunable electro-optic substrate is used to change the polarization of the light emitted from the light emitting devices. The polarization beam splitter is used to guide the light beam, depending on the polarization, in two different directions. The system, together, acts as an optical switch.
