Abstract

Short distance optical communication is required to reduce power consumption of ICT systems and continuously improve performance of datacentres and HPCs [1]. Reduced energy consumption and increased bandwidth density [2-3] are required to develop optical interconnects between chips and on chips. Therefore, lasers and detectors with ultra-low operating energy have to be connected by Si nanowire waveguides. In this context, we have developed photonic-crystal (PhC) lasers to reduce energy consumption [4]. The unique feature of our PhC lasers is that we use wavelength-scale small buried heterostructures (BH) embedded in line-defect PhC to form cavities. We call our lasers lambda-scale embedded active-region photonic-crystal (LEAP) lasers. In this paper, we report the first continuous-wave (CW) operation of LEAP lasers coupled to Si waveguides.
