THz tunable filters are key components for next-generation communication systems. In this article, we have designed a THz narrowband bandpass filter based on a double-layer frequency selective surface (FSS), which is composed of two X-shaped FSSs cascaded together with different geometric parameters. The center frequency of the double-layer structure is located between the center frequencies of the two single-layer FSSs. Based on the principle of inverse design, we employed intelligent algorithms to automatically optimize the structural parameters of the single-layer FSS. We simulated the transmission spectra of both single-layer and double-layer FSSs using finite-difference time-domain. Subsequently, FSSs were fabricated using femtosecond laser micromachining and characterized using time-domain THz spectroscopy. The experimental results are highly consistent with simulations. The designed double-layer filter exhibits a high Q factor and tunability of the center frequency by changing the spacing between the two FSS layers. Finally, based on an equivalent circuit model, we analyzed the transmission phenomenon of the nonequivalent double-layer FSS structure and attributed it to the resonances of equivalent capacitance and inductance between the FSS layers at different spacings. This approach can be applied to design tunable filters for other frequency bands.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"15 3","pages":"481-486"},"PeriodicalIF":3.9,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyze wireless data transmission within selected single and dual channels of the IEEE 802.15.3d and assess the outcomes through additional back-to-back (B2B) data transmission measurements and calibrated link budgets of the THz link. The system architecture uses on-wafer probing of a single high-power and highly linear broadband modified unitraveling-carrier photodiode (MUTC-PD). Using the MUTC-PD as THz transmitter, we report 16-QAM 100 Gbit/s 25-cm wireless links for single and dual channel data transmission with significantly low error vector magnitude (EVM) levels, that is, 12.3% and 10.9%, respectively. As for B2B demonstration, we successfully transmit 200 Gbit/s (32-QAM) in a single channel with 7.5% EVM and 160 Gbit/s (16-QAM) in dual channel with 7.8% EVM. We further display the highly linear nature of the MUTC-PD by efficient data transmission with higher modulation formats, which is also supported by the power-saturation characteristics of the PD. To the best of the authors´ knowledge, this is the first study investigating the IEEE 802.15.3d channelization compliancy through system level design and spectral verification while at the same time achieving 100 Gbit/s and beyond data rates with notably low EVM values.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"15 3","pages":"389-399"},"PeriodicalIF":3.9,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10884861","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The array is formed by vertically intersected twisted slot antennas, where enhanced combined radiation is achieved through the antiphase coupling between adjacent RTDs. Additionally, the electrode shapes are tailored to mitigate the electric field cancelation, further increasing the output power. Experimental results confirm coherent oscillation in the fabricated 2×2 array, with frequencies reaching up to 513 GHz and output power exceeding 0.4 mW at lower frequencies. Simulation results suggest that scaling up the 2-D array maintains the strong coherent coupling, despite a nonuniform amplitude distribution among the RTDs. This amplitude nonuniformity can be effectively addressed by introducing metal–insulator–metal capacitors. Furthermore, simulations also predict improved directivity with increased array scale, resulting in a low-diffusion, quasi-plane wavefront. The proposed structure holds the potential for advancing the broad application prospects of THz waves.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"15 3","pages":"431-439"},"PeriodicalIF":3.9,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The wavelength-dependent phase-delay mirrors, which were developed for this work, induce a frequency-dependent phase shift of up to <inline-formula><tex-math>$frac{pi }{2}$</tex-math></inline-formula>. This technique allows sampling of the THz-field, by tuning the laser sources in such a way that a constant frequency difference is maintained and the center frequency is shifted. In our configuration, the phase shift between transmitter and receiver arms depends only on the center frequency of the lasers. This allows for replacing the movement of a delay stage with variation of the center frequency to capture a THz trace. Consequently, measurements are not constrained by the speed of the delay line anymore. Furthermore, this phase shift is unaffected by differences in path length within the setup and does not require phase modulators. Prior simulations show that these mirrors achieve a phase shift up to <inline-formula><tex-math>$pi$</tex-math></inline-formula> in the C-band for a difference frequency of 280 GHz, which could be confirmed by our measurements. We successfully demonstrated the first application by measuring sample thickness.","PeriodicalId":13258,"journal":{"name":"IEEE Transactions on Terahertz Science and Technology","volume":"15 3","pages":"526-530"},"PeriodicalIF":3.9,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10876761","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
