“…To achieve a more clear understanding of the relationship between the O-E bandwidth roll-off, the RC limitations and the carrier transit time, an equivalent circuit model was created for the PD A. The RC-limited bandwidth (ƒ RC ) was extracted using the measured microwave reflection coefficients (S 11 ) of the photodiode [10]. Figure 6 shows the adopted equivalent circuit model used for the fitting of the measured S 11 parameters.…”

“…THz transmitter power radiated into free space is commonly measured using power meters such as pyroelectric, Golay cell, or thermopile [21], [22]. The output frequency of UTCs is seldom measured directly, but is instead calculated as the difference-frequency of the two source lasers [23]. The frequency of electronic sources such as RTDs, must be measured directly, i.e.…”

Abstract-The TERAPOD project aims to investigate and demonstrate the feasibility of ultra high bandwidth wireless access networks operating in the Terahertz (THz) band. The proposed TERAPOD THz communication system will be developed, driven by end user usage scenario requirements and will be demonstrated within a first adopter operational setting of a Data Centre. In this article, we define the full communications stack approach that will be taken in TERAPOD, highlighting the specific challenges and aimed innovations that are targeted.

“…The temporal Talbot effect, in particular, can be fruitfully employed in many ultrafast applications, such as integer, fractional, and arbitrary repetition rate multiplication (RRM) 4 , 5 , 16 , broadband full-field invisibility 17 , and noiseless intensity amplification 18 . Among these, RRM is highly appealing, especially in the case of extra-cavity scenarios like optical communications 19 , passive amplification 20 , and microwave photonics 21 , where it can be implemented by spectral amplitude and/or phase filtering 2 , 3 , 5 , 7 , 12 , 22 – 24 and provides a train of high-repetition-rate pulses that is hard to achieve in intra-cavity geometries. Besides the commonly studied temporal Talbot effect of bright pulse trains, the mixing Talbot patterns of dark pulse trains at higher RRMs was also recently investigated 7 .…”

Temporal Talbot effect, the intriguing phenomenon of the self-imaging of optical pulse trains, is extensively investigated using macroscopic components. However, the ability to manipulate pulse trains, either bright or dark, through the Talbot effect on integrated photonic chips to replace bulky instruments has rarely been reported. Here, we design and experimentally demonstrate a proof-of-principle integrated silicon nitride device capable of imprinting the Talbot phase relation onto in-phase optical combs and generating the two-fold self-images at the output. We show that the GHz-repetition-rate bright and dark pulse trains can be doubled without affecting their spectra as a key feature of the temporal Talbot effect. The designed chip can be electrically tuned to switch between pass-through and repetition-rate-multiplication outputs and is compatible with other related frequencies. The results of this work lay the foundations for the large-scale system-on-chip photonic integration of Talbot-based pulse multipliers, enabling the on-chip flexible up-scaling of pulse trains’ repetition rate without altering their amplitude spectra.
