During the last decade, subwavelength metallic cavity lasers have drawn enormous attention due to their potential application in ultra-compact photonic integrated circuits and on-chip interconnects. Aside by conventional rectangular cavities, we have previously demonstrated the Q factor improvement effect of capsule-shaped lasers with less metallic loss. However, electrical and thermal analysis are not paid enough attention even though selfheating turns out to be an important issue. In this paper, we numerically investigate the lasing property of different types of metallic lasers under electrical injection. Electrical and thermal simulations are carried out consistently, through which we confirm enhanced performance of our design by introducing a thin InAlAs electron blocking layer.
