“…In recent decades, research on on-chip lasers has focused on exploring field manipulations from different cavity designs. Early explorations of microcavity lasers utilized structures such as Fabry-Pérot (FP) cavities [7,8], distributed feedback (DFB) cavities [9][10][11][12][13], and distributed Bragg reflector (DBR) cavities [14][15][16][17][18]. In the pursuit of miniaturization with a focus on cavity or mode sizes, various solutions such as whispering gallery mode (WGM) lasers [19], photonic crystal (PhC) lasers [20], and plasmonic nanolasers [21] have been developed.…”

Owning to merits such as bandgap tunability, solution processability, large absorption coefficients, and high photoluminescence quantum yields, colloidal quantum dots (CQDs) emerged as a promising gain material to make on-chip micro/nanoscale lasers with high silicon compatibility. In this paper, we review the recent progress in CQD on-chip micro/nanoscale lasers, with a special focus on the physical properties achieved through field manipulation schemes in different types of cavities. Key aspects include manipulating and engineering wavelength, polarization, and direction as well as coupling and light extraction. Finally, we give our prospects for future research directions toward the integration of robust CQD nano/microscale lasers with photonic integrated circuits.
