(Color online) The L(I) characteristics of the QD dual-mode laser at different temperatures from 5 °C to 40 °C. The inset shows the optical spectrum of the solitary laser under asymmetric pumping and at room temperature.
DFB and Fabry-Perot cavity mode shifts as a function of temperature for different pumping conditions.
(Color online) Spectra under total asymmetric pump current for the solitary laser (strong peak at shorter wavelength) and under controlled optical feedback (two strong peaks) at (a) 5 °C and (b) 40 °C.
(Color online) Measured THz frequency difference (data decreasing with temperature) and side mode suppression ratio, data showing a minimum at 15-20 °C, as a function of temperature under the best optical feedback conditions. Solid lines are a guide for the eyes.
