Lasing characteristics.
(a) Lasing power and linewidth versus input pump power for PCSEL-I at T = 25 K. (b) Lasing spectral output (plotted in semi-log scale) above the pumping threshold (Inset: far-field image). (c) Measured polarization properties above threshold at λ = 1424 nm. (d) Lasing power and linewidth versus input pump power for PCSEL-II at T = 180 K. (e) Lasing spectral output (plotted in semi-log scale) above the pumping threshold (Inset: far-field image). (f) Measured polarization properties above threshold at λ = 1505 nm.
