Summary: In this study, carbon nanotubes (CNTs) were in situ grafted onto glass fiber (GF) via chemical vapor deposition at a low synthesis temperature (500 degrees C). By regulating the mass fractions of CNTs, the quantum tunneling effect among CNT nanoparticles was triggered, resulting in high sensitivity of the CNT-grafted GF textiles to structure-guided ultrasonic waves in the frequency range from 175 to 375 kHz. The CNT-grafted GF textiles demonstrated great potential in developing hybrid functional composites, with negligible degradation in mechanical attributes as confirmed by ASTM-complied tests (ASTM C1557 and D3039).

Summary: The propagation of ultrashort pulses in optical fibers is crucial for the development of light sources and photonic technologies, but it often requires extensive numerical simulations. A new approach using recurrent neural networks can predict complex nonlinear propagation solely from the input pulse intensity profile, aiding in designing experiments for pulse compression and ultra-broadband supercontinuum generation.

Summary: In this study, the time-scale laser-induced voltage (LIV) of air under KrF excimer laser irradiation was investigated. The LIV response was fitted using a sum of three exponential functions, with the fitted parameters being influenced by the bias voltage Vb and the laser energy Ein. Higher Vb resulted in significant LIV. An exponential relationship was observed between Ein and the amplitude (Vp) of the LIV signal. By adjusting the adjustable resistor, the LIV trace became almost triangular and symmetrical, due to the impedance effect and limited response time by the laser pulse duration. As a potential application, the LIV of air presented a viable method for single-pulse laser detection.

Summary: Fabricating electronic and optoelectronic devices using a facile electrode fabrication process with SWCNT films leads to improved device performance. Dry-transferred SWCNT films as transparent electrodes in Schottky diodes for photodetector applications increase light absorption in photoactive MoS2 channels. The enhanced photodetection is attributed to FN tunneling and internal photoemission of charge carriers excited from indium tin oxide across the MoS2 layer.

Summary: The authors demonstrate analogue reversed Cherenkov radiation in MoO3 at mid-infrared frequencies, and show that stacking hBN layers on the surface of MoO3 can enhance the radiation angle and quality factor. Reversed Cherenkov radiation is highly desired as it can effectively separate radiated light from fast charges, but it has been challenging to achieve in the mid-infrared range due to significant loss in conventional artificial structures.

Summary: Researchers have successfully created heteronuclear multicolor soliton compounds composed of chirp-free conventional solitons and chirped dissipative solitons in mode-locked fiber lasers by introducing convex-concave frequency phases. Despite different lasing wavelengths, the dissipative solitons always overlapped with the conventional solitons, resulting in modulated wavepackets. The resonant sidebands of the two solitons followed the same phase-matching principle determined by the absolute value of cavity dispersion. Experimental results were fully substantiated by simulations, confirming that the overlapping of two solitons was dominated by the co-action of saturable absorption and group-delay compensation. It was demonstrated that the phase-managed dissipative system could support multicolor soliton compounds with distinct properties, providing an effective platform to study the interaction of dissimilar nonlinear wavepackets.
