Two-Dimensional Bi2Sr2CaCu2O8+δ Nanosheets for Ultrafast Photonics and Optoelectronics

The interaction of 2D materials with ultrashort laser excitation generates fiber soliton pulses with extreme nonlinear absorption characteristics, which are essential for generating ultrafast pulses. However, searching for suitable nanomaterials to achieve versatile photonic properties is difficult. Factors such as cost, manufacturing process complexity, optical response time, and nonlinear absorption effects make the balance between high performance and low cost a constant challenge, greatly hindering the research and development of ultrafast photonics technology. For fiber soliton pulse systems, 𝜸-MnO 2 , as a transition metal oxide (TMO), shows excellent potential among many candidate nanomaterials due to its rich narrow-band optoelectronic microstructural features and nonlinear optical properties. In this work, this fundamental trade-off is overcome and 𝜸-MnO 2 is investigated as a nonlinear optical material for multifunctional fiber soliton pulsed lasers. The outputs of conventional soliton pulses, 23rd order harmonic soliton-molecule picosecond pulses, continuous and soliton pulse waves coexist in dual-wavelength, and soliton rain pulses are obtained simultaneously, successfully achieving a technological breakthrough in nanophotonics and pulse dynamics. It is demonstrated that MnO 2 has a broad application prospect for generating nonlinear effects such as fiber optic soliton pulses, which provides an effective and rich theoretical support for developing ultrafast photonics of narrow-band optoelectronic materials.

The outstanding chemical and physical properties of 2D materials, together with their atomically thin nature, make them ideal candidates for metaphotonic device integration and construction, which requires deep subwavelength light–matter interaction to achieve optical functionalities beyond conventional optical phenomena observed in naturally available materials. In addition to their intrinsic properties, the possibility to further manipulate the properties of 2D materials via chemical or physical engineering dramatically enhances their capability, evoking new science on light–matter interaction, leading to leaped performance of existing functional devices and giving birth to new metaphotonic devices that were unattainable previously. Comprehensive understanding of the intrinsic properties of 2D materials, approaches and capabilities for chemical and physical engineering methods, the resulting property modifications and novel functionalities, and applications of metaphotonic devices are provided in this review. Through reviewing the detailed progress in each aspect and the state-of-the-art achievement, insightful analyses of the outstanding challenges and future directions are elucidated in this cross-disciplinary comprehensive review with the aim to provide an overall development picture in the field of 2D material metaphotonics and promote rapid progress in this fast emerging and prosperous field.

The transfer of two-dimensional materials from grown substrates onto target substrates is critical for device applications and postgrown analysis. The traditional transfer method for as-grown two-dimensional materials requires a wet chemical etching process that damages the crystals and the substrates. These issues deteriorate the electrical and optical performances of two-dimensional-material-based devices fabricated afterward. Herein, we developed an etching-free method and nanoimaging for transferring and analyzing monolayers of MoS2 onto arbitrary substrates using polyurethane as a sacrifice polymer. The polymer layer and the MoS2 crystals can be peeled off from the substrate by tweezers and transferred to any substrate. We analyzed the transferred samples to a glass coverslip substrate with optical microscopy, atomic force microscopy, tip-enhanced Raman spectroscopy, and tip-enhanced photoluminesce spectroscopy. Also, we transferred monolayers of MoS2 to a transmission electron microscopy grid and acquired scanning electron microscopy together with high-resolution scanning transmission electron microscopy images. The results of nanoimaging indicate that the method preserved the sample’s optical and structural properties and avoid undesirable cracks, wrinkles, and polymer residues. The etching-free transfer method of as-grown two-dimensional materials will improve the quality of transferred samples enhance the devices’ performance.
