Fig. 6: Room temperature lasing of subwavelength wire, square cavity, and micro-disk lasers.
From: A monolithic InP/SOI platform for integrated photonics
a, e, i Room-temperature PL spectra of the subwavelength wire, square cavity, and micro-disk lasers, respectively. Inset shows the corresponding emission images below and above threshold. b, f, j Light–light (L–L) curve and linewidth narrowing of corresponding lasers. Calculated cross-sectional (c, g, k) and top-view (d, h, l) lasing mode profiles of the InP lasers
