We present the design of an electrically pumped metallic cavity laser based on optical, electrical and thermal simulations. By inserting an InAlAs blocking layer, leakage current is effectively suppressed, leading to 50% reduction of threshold current together with better thermal stability. Through combined optical and electrical analyses, the insulation layer thickness is set to be 60 nm, where the...
We propose and numerically investigate a novel hollow hexagonal InGaAs microdisk laser on a silicon substrate, which can be fabricated by the micro-channel selective-area (MC-SA) MOVPE growth technique. By simply introducing an etched hole with a suitable radius at the center of the hexagonal microdisk, quasi-whispering-gallery modes emerge and the cavity Q factor improves drastically from 371 to...
We propose novel 1.55-µm capsule-shaped metallic-cavity lasers with curved facets to reduce plasmonic losses. Significant reduction of threshold current from 291 µA to 60 µA is demonstrated with effective modal volume of 0.45 µm3.
