Abstract

We present the optoelectronic frequency and amplitude modulation of a terahertz quantum cascade laser, achieved by implementing a graphene loaded split ring resonator array into an external cavity feedback set-up. Amplitude modulation depths as high as 100% are achieved and the output frequency is lithographically and optoelectronically tuned.
