Аннотация:As optical communications and networks get more complex, integrated, and to ever smaller scales, we are moving ever closer to the future of optoelectronic chips where key components of an optical system are all integrated on a chip, including especially light sources.This talk will discuss some of the most serious challenges for such on-chip light sources including size, energy efficiency, and silicon integration.More specifically, how to make semiconductor lasers smaller than the diffraction limit and more energy-efficient than 10fJ per bit of information transmitted?How to make light sources compatible with Silicon?We will try to show how potential solutions to these grand challenges could be provided by going small or nano.How one could take advantage of nanoscale semiconductor materials and devices to address these issues.The talk will overview progress made in the last 15 years and provide personal perspectives of the future.Specific materials, structures, and devices to be discussed include: 1) nanolasers based on plasmonic or metallic cavities and 2) nanolasers based on 2D transition metal dichalcogenides (TMCs) as optical gain materials for nanolasers.
