“…The quadruple reflected laser profile ablates part of the localized region on the black dye medium to form a CG as a set of semi-circles ( Figure 1d). Both structures were gratings resulting from the laser interference produced from various regions of the concave mirrors which produced non-linear structures 36,[38][39][40]…”

Buildings, bridges, and aircrafts are frequently exposed to fluctuation loads which could start with a fine crack that instantly lead to unpredictable structure failures. The stationary strain sensors can be utilized, but they are costly and only detect limited deformations forms and sizes. Here, we fabricated photonic strain sensors on adhesive tapes which can provide realtime monitoring of irregular surfaces. Holographic interference patterning was used to produce non-linear curved nanostructures of 1D of (900 nm × 880 nm) and 2D from black dye film on a robust uniform adhesive layer and heat resistance tape. The patterned structure of the black dye was stable in broad pH environments. Diffracted light from the curved nanostructure detected the signal during structural damage, shift or material tear of 5 µɛ at less than 1.3 N cm-2. Additionally, the 2D nanostructure detected a surface change from x or y axis. Tilting the 1D structure within the range of 0.3° to 14.2° provided visible wavelength changes under broadband light to reveal early deflection signs. The curved nonpatterns could be also used for

“…8,9 Because of the unique physical properties of graphene, interaction of the electromagnetic field and graphene materials can lead to many quantum coherent effects, such as electromagnetic-induced transparency (EIT). [10][11][12] In the last few years, based on the EIT effect, 13,14 many interesting quantum optical phenomena have been studied in atomic systems and semiconductor nanostructures, for example, the electromagnetically induced grating (EIG), [15][16][17] optical bistability and multistability [18][19][20] and switching, 21 Kerr nonlinearity enhancement, [22][23][24][25] weak-light optical solitons [26][27][28][29][30][31] and so on. More recently, much attention has also been paid on the study of EIT related quantum interference effects in the graphene quantum system.…”

Graphene nanomaterials exhibit excellent optical properties when interacting with electromagnetical fields, which plays an important role in a wide range of applications such as optical communications, optical storage and other fields. Based on the electromagnetically induced transparency (EIT) effect, we investigate control of slow light in the Landau quantized graphene system with different three-level and four-level coupling schemes. Utilizing the EIT effect, group velocity of the probe fields can be significantly reduced and well controlled by manipulating Rabi frequencies and detunings of the coupling lasers as well as probe detuning. Furthermore, probe light with different frequencies can even be controlled in different EIT windows in the graphene system with the four-level scheme, which may find applications in signal selection and discrimination. This work can provide reference for the design of graphene-based quantum devices and have potential applications in optical communications and optical quantum information processing, etc.

“…In a recent paper [26], the author proposed 1D and 2D electromagnetically induced polarization diffraction grating based on EIT for realization polarization-dependent multiple beam splitting in the Raman-Nath limit. An electromagnetically induced phase diffraction grating controlled by spontaneous generated coherence (SGC) in atomic systems is studied in [27,28] The possibility of significant improvement of the intensity of higher-order diffractions via relative phase between applied laser fields due to the existence of SGC is shown. The authors [29] propose a gain-phase diffraction grating based on spatial modulation of the cross-Kerr nonlinearity in a Raman active medium.…”

We propose and analyze an efficient scheme for the one-and two-dimensional atomic gratings based on periodic spatial modulation of the Raman gain and dispersion, which we name the Raman induced diffraction gratings (RIDGs). There are fundamentally different from those based on electromagnetically induced transparency. As the probe field propagates along the direction normal to the standing pump wave, it can be effectively diffracted into high-order directions. The grating is a superposition of an amplitude and a phase gratings. We identify the conditions when all highorders diffraction are amplified. In addition, we also show that diffraction of a probe field could be dynamically controlled using an additional laser field. With its help, it is possible to suppress or amplify diffraction beams. The RIDGs can be considered as all-optical multi-beam splitters with amplification.
