Abstract
Dual-mode hybrid injection-locking scheme is reported over an L-band InAs/InP quantum-dash laser to generate tunable millimeter (MMW) and Terahertz (THz) beat frequencies. In addition to the inherent enhancements that are provided by injection locking, the system provides comparable high dual-mode peak power, side mode suppression ratio (SMSR) up to 30 dB, and large beat frequency tunability of ∼1.7 THz. As such, four different beat frequencies are demonstrated, namely 62.6- and 263-GHz MMW and 1.21- and 1.75-THz signals. The stability of the generated waves is then investigated showing a minimal fluctuation of 0.35 dB and 0.1 dB in the SMSR and peak power, respectively.
