Replication Data for: Electrically Tunable Topological Notch Filter for THz Integrated Photonics
No full textElectromagnetic filtering is essential for emerging integrated photonic technologies and widely adaptable processing of high-bandwidth signals. Conventional electro-optic modulator-based photonic approach for signal filtering at microwave frequencies could not be implemented at terahertz (THz) frequencies due to the unavailability of the THz signal-driven optical modulator. Here, we demonstrate an electrically tunable on-chip THz photonic notch filter based on the topologically protected valley hall waveguide-cavity platform. Our device shows a significantly large notch suppression depth of more than 20 dB with a return loss of 13 dB at in the entire tuning range of notch frequency. The feedback control circuit enabled precise control of the notch frequency shift with a minimum step size of 7 MHz. Our work extends the application of topological photonic crystals in developing THz integrated photonic devices for transformative technologies, including sixth generation (6G) communication and high-resolution spectral sensing
Related Data for: Photonic Supercoupling in Silicon Topological Waveguides
No full textWaveguide interconnect coupling control is essential for enhancing the chip density of photonic integrated circuits to incorporate a growing number of components. However, a critical engineering challenge is to achieve both strong waveguide isolation and efficient long-range coupling on a single chip. Here, a novel photonic supercoupling phenomenon is demonstrated for waveguide coupling over separation distances from a quarter to five wavelengths, leveraging tunable mode tails and the vortex energy flow in topological valley Hall system. A supercoupled integrated chip is demonstrated, realizing a 91% coupling ratio and a -30 dB isolation over 2.8λ waveguide separations simultaneously. Supercoupled devices are further showcased including a waveguide-cavity system with 3.2λ excitation distance, and a waveguide directional supercoupler with a compact coupling area of nearly λ2/4, which outperform conventional devices. Supercoupling provides new degrees of freedom for optimizing coupling and isolation between photonic integrated components, facilitating new applications in on-chip sensing, lasing, and telecommunications

Pulsed SILAC-based proteomic analysis unveils hypoxia- and serum starvation-induced de novo protein synthesis with PHD finger protein 14 (PHF14) as a hypoxia sensitive epigenetic regulator in cell cycle progression
No full textHypoxia is an environmental cue that is associated with multiple tumorigenic processes such as immunosuppression, angiogenesis, cancer invasion, metastasis, drug resistance, and poor clinical outcomes. When facing hypoxic stress, cells initiate several adaptive responses such as cell cycle arrest to reduce excessive oxygen consumption and co-activation of oncogenic factors. In order to identify the critical novel proteins for hypoxia responses, we used pulsed-SILAC method to trace the active cellular translation events in A431 cells. Proteomic discovery data and biochemical assays showed that cancer cells selectively activate key glycolytic enzymes and novel ER-stress markers, while protein synthesis is severely suppressed. Interestingly, deprivation of oxygen affected the expression of various epigenetic regulators such as histone demethylases and NuRD (nucleosome remodeling and deacetylase) complex in A431 cells. In addition, we identified PHF14 (the plant homeodomain finger-14) as a novel hypoxia-sensitive epigenetic regulator that plays a key role in cell cycle progress and protein synthesis. Hypoxia-mediated inhibition of PHF14 was associated with increase of key cell cycle inhibitors, p14ARF, p15INK4b, and p16INK4a, which are responsible for G1-S phase transition and decrease of AKT-mTOR-4E-BP1/pS6K signaling pathway, a master regulator of protein synthesis, in response to environmental cues. Analysis of TCGA colon cancer (n=461) and skin cancer (n=470) datasets revealed a positive correlation between PHF14 expression and protein translation initiation factors, eIF4E, eIF4B, and RPS6. Significance of PHF14 gene was further demonstrated by in vivo mouse xenograft model using PHF14 KD cell lines
