Schematic of the long-wavelength VCSEL.
(a) VCSEL output power vs pump power at different temperatures. The offset between the active layer PL peak and cavity resonance is at . (b) VCSEL spectrum at four temperatures for an incident power of . The spectra at different temperatures are overlaid. (c) A histogram of the VCSEL light output at for a pump power of .
(a) Small-signal modulation response of the VCSEL at three different output powers. The horizontal dashed line is the mark. (inset) of the modulator. (b) of the VCSEL (dashed lines) after correcting for the frequency response of the external modulator. The solid lines respresent a least-squares fit to Eq. (1). The horizontal dashed line is the mark.
