There is an urgent need to dramatically improve the interconnectivity between photonics domain and electronics domain for multi-functional photonic/electronic system integration. The mismatch in physical scaling between photonics and electronics presents a significant challenge in the high density integration of photonics and Si compatible optoelectronics. The path towards truly scalable, high density multi-functional photonic/electronic integration shall be based upon nanomanufacturing processes for heterogeneous integration of different material systems on nanophotonic platforms, such as photonic crystals, quantum dots, plasmonics and other nanoscale structures.
In this talk, we will report our work on nanophotonic devices and the associated fabrication processes, mostly based on the top-down and bottom-up integration on photonic crystal platforms on silicon and other foreign substrates. Spectrally-selective infrared photodetectors based the hybrid integration of quantum dots and photonic crystal cavities will be discussed for hyper-spectral imaging and silicon photonics applications. Solution processed one-dimensional photonic crystals and distributed Bragg reflectors (DBRs) are being developed for light emitters and detectors on Si. We will also report other collaborative work on ultra-compact filters/detectors on Si, based on the top down lithographic patterning and bottom up stacking processes. These nanomanufacturing processes hold great promises for nanophotonic devices and flexible photonic system integrations, suitable for applications ranging from optical interconnect systems and silicon photonics, to infrared sensing and flexible displays. The projects are supported by NSF Nanomanufacturing, AFOSR, AFRL/CONTACT, and NASA TSGC programs.
