Abstract

THz wireless communications has established itself as a self-contained research field within THz technology. Following the field´s general trend to enhance system transport capacity by increasing the formats´ carrier frequencies and payloads, we report a novel scheme for generating a 2.5 Gb/s data signal on a 625 GHz carrier, its transmission over lab distance, and error-free detection. Duobinary baseband modulation on the transmitter side generates a signal with a sufficiently narrow spectral bandwidth to pass an up-converting frequency multiplier chain. Power, bit-error rate (BER), and signal-to-noise ratio (SNR) measurements on the receiver side describe the signal performance.
