“…[7][8][9][10] The tube waveguide has been demonstrated both theoretically and experimentally to support whispering gallery modes (WGM) circulating along its circumference. 6,[11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] The light can be evanescently coupled between the tube and a straight waveguide once their separation is made adequately small, typically within a fraction of the wavelength of the propagating light. Several research groups have already demonstrated 3D photonic integration using the tube waveguide.…”

“…Several research groups have already demonstrated 3D photonic integration using the tube waveguide. 11,20,24,26 However, a monolithically integrated version of the tube waveguide to a planar ridge waveguide coupling has not yet been demonstrated experimentally. The result we report here is a monolithically integrated resonator-based vertical photonic coupler on silicon platform.…”

We demonstrate a self-rolled-up microtube-based vertical photonic coupler monolithically integrated on top of a ridge waveguide to achieve three-dimensional (3D) photonic integration. The fabrication process is fully compatible with standard planar silicon processing technology. Strong light coupling between the vertical coupler and the ridge waveguide was observed experimentally, which may provide an alternative route for 3D heterogeneous photonic integration. The highest extinction ratio observed in the transmission spectrum passing through the ridge waveguide was 23 dB. V

“…The performance of other 2D materials, such as 2D topological insulators [ 60 ] and 2D self‐crimping materials, [ 61 ] has also proved to be excellent in THz detection and 2D materials are likely to play an important role in the future. The diversity and excellent physical properties of 2D materials enable their significant advantages in THz detection.…”

5G communication has begun commercial deployment. To maintain the sustainability and competitiveness of wireless communication systems, various industries and academic institutions around the globe are designing the framework for 6G communications. Compared with the previous generations of communication systems, 6G will be revolutionary, with unprecedented requirements in data transmission rates, delays, and global coverage. Many promising technologies in 6G systems, including terahertz communication, ultra‐large‐scale antenna arrays, large‐scale intelligent surfaces, quantum communication, and computing, have differing material requirements compared with previous systems. With the development of materials science, an increasing number of new materials will play important roles in 6G communications. Herein, the high demand of 6G systems is introduced first in this review, and recent advances of new materials having a broad variety of applications with great potential in 6G systems are systematically summarized. Perspectives on the research areas that require special attention are also presented.

“…By embedding active media (e.g., quantum dots and quantum wells) into one of the strained layers, microtubes can function as on-chip coherent light sources [6][7][8][9][10][11][12]. Other novel microtube-based PIC components, such as filters, modulators, directional couplers, and phototransceivers have also been realized [13][14][15]. The applications of microtubes are not limited to photonic integrated devices.…”

We report on theoretical and experimental investigation of azimuthal and longitudinal modes in rolled-up microtubes at telecom wavelengths. These microtubes are fabricated by selectively releasing a coherently strained InGaAs/GaAs bilayer. We apply planar waveguide method and a quasi-potential model to analyze the azimuthal and longitudinal modes in the microtubes near 1550 nm. Then we demonstrate these modes in transmission spectrum by evanescent light coupling. The experimental observations agree well with the calculated results. Surface-scattering-induced mode splitting is also observed in both transmission and reflection spectra at ~1600 nm. The mode splitting is in essence the non-degeneracy of clockwise and counter-clockwise whispering-gallery modes of the microtubes. This study is significant for understanding the physics of modes in microtubes and other microcavities with three-dimensional optical confinement, as well as for potential applications such as microtube-based photonic integrated devices and sensing purposes.
