Abstract: Nanophotonics technology has the potential to revolutionize numerous future applications that rely on the ability to integrate it on a chip to augment and/or interact with other signals (e.g., electrical, chemical, biomedical, etc.). For example, future computing and communication systems will need integration of nanophotonic structures, devices and circuits with electronics and thus require miniaturization of photonic materials, devices and subsystems. Another example involves integration of microfluidics with nanophotonics for healthcare applications. We have advanced the nanophotonics technology by establishing design, fabrication and testing tools ranging from nanoscale engineered dielectric metamaterials, nanodevices, and circuits for various systems applications. Our most recent work emphasizes the construction of optical subsystems directly on-chip, with the same lithographic tools as the surrounding electronics. This has been made possible by the advances in lithographic tools, which can now create features significantly smaller than the optical wavelength and is predicted to reach as fine as 11 nm by 2020. Arranged in a regular pattern, subwavelength features act as a metamaterial whose optical properties are controlled by the density and geometry of the pattern and its constituents. As specific examples of our most recent work towards these goals, we will present nanoscale engineered second order nonlinearities in silicon and various composite metal-dielectric-semiconductor gain geometries used to create new types of nanolasers for chip-scale integration of optical information systems.
