In this present work, InAs/InGaAs/GaAs quantum-dot PCSEL was fabricated by epitaxial regrowth method using molecular beam epitaxy (MBE). The laser heterostructure with active region of three layers of InAs dots-in-well (DWELL) was optimized for 1200 nm emission wavelength design. The performance and characteristics of PCSELs were investigated and analyzed by optical pumping at room temperature.
