Abstract

We have developed InP based 1.55 μm lasers epitaxially grown on (001) Si substrates for photonics integration. To overcome the fundamental material challenges associated with mismatch III-V on Si hetero-epitaxy, a Si V-groove epitaxy platform was established, leading to device quality III-V nanostructures and thin films. Combining metal organic chemical vapor deposition (MOCVD) grown 1.55 μm InAs QDs and the InP/Si thin film templates, we have achieved electrically driven 1.55 μm QD lasers on Si operating at room-temperature. To reduce device footprint and energy consumption, a buffer-less integration path by growing InP nano-ridge lasers on pre-patterned silicon-on-insulators (SOI) wafers has been explored. Material and device characterizations and an outlook for device component integration is discussed.
