Particular emphasis in on active photonics that utilize nanostructures in and around the active region (where a critical device function occurs). Subwavelength optical structures for tailoring cavity and coupling aspects are relevant as well as low dimensional and 2D nanostructures that provide critical optoelectronic device functionality. Performance enhancements created by use of nanostructures is of keen interest and the focus is on how to incorporate such structures with necessary fidelity and precision to achieve the enhanced function. Some of the areas to be explored include:
1. Nanofabrication issues related to etching of nanostructures – creation of smooth interfaces and surfaces to reduce optical scattering and nonradiative recombination.
2. Nanolithography considerations related to achieve nano-sized (~100 nm or less) structures for quantum or optical effects desired. Ideas include use of e-beam, deep UV, nanoimprint, or other approaches. Various materials, processes, and templating ideas should be discussed.
3. Nanopatterning and nanostructuring for epitaxial crystal growth should be explored in this context. Ideas include nanowire placement and growth, core-shell and other passivation issues, block co-polymer templating, and other nanoscale templating processes.
4. Hybrid integration techniques to take advantage of nanostructures – both 2D materials and photonics based upon chemically synthesized nanostructures could be explored (e.g. colloidal quantum dots).
The motivation for the topical is to explore enhanced optoelectronic device performance thru the utilization of nanostructures. The photonic device regimes affected include ultra-narrow linewidth lasers, high efficiency nanolasers, modulators and detectors, high-speed devices, switches and couplers and other active devices. The physics of low dimensional and 2D materials that promises for improved performing photonics will be discussed in light of the goal of practical implementation.
