Design and Development of Electrically Pumped Coaxial Nanoscale Laser for On-chip Optical Communication - TOPIC STIR
Abstract
Small footprints, low power consumption, and high operating speeds are some of the desirable attributes of future chip-scale photonic integrated circuits (PIC). This has fueled some of the recent activities in developing nanolasers as one of the key components of such integrated systems. To overcome the challenges facing laser miniaturization, drastically new designs based on metallic nano-cavities have been pursued. Along these lines, optically pumped nanolasers based on a metallic coaxial architecture, as well as electrically pumped nanolasers utilizing metallo-dielectric structures were demonstrated in the past. In the course of this STIR project, the PIs performed a feasibility study for developing electrically pumped coaxial nano-lasers that could be effectively coupled to a silicon interconnect via a plasmonic waveguide section. To this end, lasing has been demonstrated in coaxial nano lasers fabricated on wafers capable of becoming electrically pumped. A rate equation model is developed to calculate the lasing threshold as well as the highest possible speed for such devices under optical pumping. Effort also has been directed towards accurately measuring the second order coherence function of optically pumped nanolasers.
