Terahertz oscillators using AlAs/InGaAs resonant tunneling diodes with deep and thin quantum wells are reported. Although a thin well has been shown to be effective for highfrequency oscillation until now due to a reduced electron dwell time, it caused an increase in bias voltage. We introduce a deep well with indium-rich InGaAs to maintain or even to reduce the bias voltage. Current-voltage and oscillation characteristics are compared between the quantum wells with 3.5-nm-thick In 0.8 Ga 0.2 As and 3-nm-thick In 0.9 Ga 0.1 As. The highest oscillation frequency was 0.96 THz for the former while 1.27 THz for the latter without increase in bias voltage.

“…Recent results for THz wireless links employing photonic carrier generation at frequencies ranging from 200 GHz to 400 GHz have indeed demonstrated the possibility of transmitting wireless data at more than 1 Gb/s. Above 250 GHz, detection has been limited to incoherent envelope detection using Schottky barrier diode (SBD) detectors [50][51][52], but the demonstration of data transmission at up to 28 Gb/s [52] clearly shows the potential for high bandwidth wireless transmission at these carrier frequencies, although, due to transmission impairments and the low signal powers available, a compromise will need to be found between carrier frequency and spectral efficiency.…”

Abstract:We present a review of recent developments in THz coherent systems based on photonic local oscillators. We show that such techniques can enable the creation of highly coherent, thus highly sensitive, systems for frequencies ranging from 100 GHz to 5 THz, within an energy efficient integrated platform. We suggest that such systems could enable the THz spectrum to realize its full applications potential. To demonstrate how photonics-enabled THz systems can be realized, we review the performance of key components, show recent demonstrations of integrated platforms, and give examples of applications.

Abstract:We propose and experimentally demonstrate THz photonic wireless communication systems with 16-QAM modulation in the 375-450 GHz band. The overall throughput reaches as high as 80 Gbit/s by exploiting four THz channels with 5 Gbaud 16-QAM baseband modulation per channel. We create a coherent optical frequency comb (OFC) for photonic generation of multiple THz carriers based on photo-mixing in a uni-travelling carrier photodiode (UTC-PD). The OFC configuration also allows us to generate reconfigurable THz carriers with low phase noise. The multiple-channel THz radiation is received by using a Schottky mixer based electrical receiver after 0.5 m free-space wireless propagation. 2-channel (40 Gbit/s) and 4-channel (80 Gbit/s) THz photonic wireless links with 16-QAM modulation are reported in this paper, and the bit error rate (BER) performance for all channels in both cases is below the hard decision forward error correction (HD-FEC) threshold of 3.8e-3 with 7% overhead. In addition, we also successfully demonstrate hybrid photonic wireless transmission of 40 Gbit/s 16-QAM signal at carrier frequencies of 400 GHz and 425 GHz over 30 km standard single mode fiber (SSMF) between the optical baseband signal transmitter and the THz wireless transmitter with negligible induced power penalty.
