摘要

We report an ultra-wide tunable single- and double-mode InAs/InP quantum dot (QD) external-cavity (EC) laser in a Littrow configuration. By combining the high modal gain of the QD material in the long wavelength range and an anti-reflection/high-reflection facet coating, the entire single-mode tuning range was increased up to 190 nm under a relatively low constant pulsed injection current. Furthermore, the tunable range was further increased to 230 nm at different bias currents. In addition, a mode spacing as wide as 100 nm was achieved using the same QD-EC device in the dual-mode operation, corresponding to a frequency difference of approximately 11 THz.
