We strive to fill the need of chip-scale CMOS-compatible coherent sources that are sub-wavelength in all three physical dimensions, EM isolated from the surrounding photonic circuits and operate at room temperature. We demonstrate room temperature laser emission from optically pumped silicon compatible metallo-dielectric cavities that are sub-wavelength in all three dimensions. These lasers are hybrid devices integrating III-V gain with silicon. We also demonstrate 77K-160K laser emission from electrically pumped metallo-dielectric cavities that are sub-wavelength in all three dimensions. We also demonstrate a thresholdless laser design. Room-temperature sub-wavelength lasers can be utilized in various areas including integration with the CMOS platform, the development of arrays of ultra-compact individually controlled coherent sources spanning C-band which enable data rates of more then 40 GB/s and bio-sensing.
