DOI: 10.35848/1882-0786/ab95f0
Abstract: GaN-based microdisk lasers grown on Si have a wide application prospect in communication and Si photonics. However, the relatively large threshold current and thermal resistance often cause a very high junction temperature, which severely affects… read more here.
