Investigate the direct intensity modulation and wireless data transmission features of terahertz-oscillating resonant tunnelling diodes.
Measured frequency response of RTD oscillators.
Reduced parasitic elements in external circuit to enhance modulation frequency.
Demonstrated wireless data transmission using amplitude shift keying at 542 GHz.
Achieved a 3 dB cutoff modulation frequency of up to 4.5 GHz.
Cutoff frequency for wireless transmission was 1.1 GHz with bit error rates of 2×10−8 and 3×10−5 at 2 and 3 Gbit/s, respectively.
