“…First demonstrated in 2004 for the synthesis of infrared photonic crystals [2], two-photon polymerization is now widely employed for the synthesis of three-dimensional structures with a spatial resolution ranging from nm-to µm-scales [3][4][5]. Contemporary applications of this technique have enabled the fabrication of complex optical components [6][7][8]. Recently, 3D-DLW has been successfully employed for the synthesis of metamaterials [9][10][11][12].…”

“…The optical components and materials fabricated using 3D-DLW cover a very wide spectral range from the ultraviolet (UV) through the visible (VIS ) to the near-infrared (NIR) [13][14][15][16][17]. In addition, 3D-DLW-based fabrication of micro-optical elements with functional coatings and the manufacturing of metasurfaces have attracted much attention [8,[18][19][20][21].…”

The polymers IP-Dip, IP-L, and IP-S are among the most commonly used photo-resists employed for the rapid prototyping of optical components using two-photon polymerization. Despite the widespread use of these polymers, measured data on their optical properties is scarce. Recently, the refractive index n of these polymers has been determined in the visible and nearinfrared spectral range. However, the accurate optical properties including extinction coefficient κ in the ultraviolet spectral range have not been reported yet. Here we report on accurate, ellipsometric measurements of the complex dielectric functions of two-photon polymerized IP-Dip, IP-L, and IP-S in the spectral range from 210 nm to 1500 nm. Model dielectric functions composed of oscillators with Lorentz, Gaussian, and Tauc-Lorentz broadenings are presented for all investigated polymers.

“…Advanced functionality and operation regimes can be realized in photonic structures made of linear, isotropic, passive materials, in which the effects of different periodicities are properly combined. Among them, one should mention those known as photonic crystal (PhC) gratings [1][2][3][4][5]. Initially, PhC gratings were proposed for the reflection mode [1,6] and later for the transmission mode [3,7].…”

“…Initially, PhC gratings were proposed for the reflection mode [1,6] and later for the transmission mode [3,7]. The interest in PhC gratings has been growing in the connection with diffraction-inspired asymmetric transmission [2][3][4][5] and locations of frequency-domain thresholds for higher diffraction orders [7], which are unusual compared to the classical grating theory [8]. To obtain these regimes, the spatial inversion symmetry must be broken.…”

Two types of single-beam deflection and asymmetric transmission in photonic structures without interface corrugations

et al. 2016

We study single-beam deflection and asymmetry in transmission, two aspects of the same phenomenon that appear in the topologically simple, nonsymmetric, photonic crystal (PhC)-based structures without corrugations at the interfaces. Strong diffractions enabling efficient blazing, i.e., redistribution of the incident wave energy in favor of the desired higher diffraction order(s), can be achieved owing to the defect-like layer(s) embedded in a regular slab of PhC. The main features, together with the peculiarities of the two basic transmission types and relevant coupling and deflection scenarios, are discussed, for one of which a part of the PhC works in the evanescent-wave regime. Performances are suggested, in which efficient single-beam deflection and asymmetry in transmission can be obtained even when the irregular layer is deeply embedded. More than 97% of the incident wave energy can be converted into a single deflected beam that is associated with the first negative diffraction order, even though the entire structure is nonsymmetric and the diffractive element is located at some distance from the incidence interface.

“…However, the reported structures are rather narrow band or limited to GHz range which is not favorable for optical applications, or they have low asymmetric transmission value, near one fifth. It should be noted that reciprocal optical diodes have also been demonstrated in the realm of photonic crystals and parity‐time symmetric waveguide . In addition, it is worth mentioning that strong polarization conversion by metamaterials has been demonstrated in the terahertz region, which potentially could be scaled to the optical wavelengths to realize broadband asymmetric transmission.…”

ideal optical isolator that can transmit and block any spatial mode in the opposite two directions. However, these approaches are quite challenging, especially at the integrated and complementary metaloxide semiconductor (CMOS) compatible system level.Metamaterials, engineered materials with extraordinary optical properties originated from subwavelength structures, provide an alternative simple solution to realize optical diodes via mode conversion between specific modes, even though the system is completely reciprocal. The underlying mechanism arises from the spatial symmetry breaking. Different reciprocal optical diodes have been proposed and demonstrated by employing various metamaterials and metasurfaces. For instance, asymmetric transmission for circularly polarized light has been realized by chiral metamaterials including split-ring resonator and fish-scale patterns. [6][7][8][9][10][11] Asymmetric transmission of linear polarization has been also reported using asymmetric gratings, [12,13] grating-patterned metal-dielectric bilayer [14] and metal-dielectric multilayer, [15] and specifically designed unit cell including bilayer metallic strips, [16] half-gammadions, [17] a U-shaped resonator, [18][19][20] and L-shaped bilayer structures. [21,22] However, the reported structures are rather narrow band or limited to GHz range which is not favorable for optical applications, or they have low asymmetric transmission value, near one fifth. It should be noted that reciprocal optical diodes have also been demonstrated in the realm of photonic crystals [23][24][25][26] and parity-time symmetric waveguide. [27][28][29] In addition, it is worth mentioning that strong polarization conversion by metamaterials has been demonstrated in the terahertz region, [30,31] which potentially could be scaled to the optical wavelengths to realize broadband asymmetric transmission.In this paper, we present numerical and experimental demonstrations of an optical metamaterial composed of two layers of half-gammadion structures for asymmetric transmission of linearly polarized light with up to 50 THz bandwidth in the short-wavelength infrared region. We have developed microscopic dipolar description to unveil the fundamental mechanism of the asymmetric transmission. Furthermore, the performance is highly robust even under misalignment errors, which might take place in the fabrication process. Our research findings promise novel applications such as on-chip optical computing, information communication, and prevention of unwanted interferences and interactions in integrated photonic circuits.As an analog of electrical diodes, optical diodes enable asymmetric transmission or one-way transmission of light. Here, a thin bilayer metamaterial supporting asymmetric transmission is experimentally demonstrated for linearly polarized light but not for circularly polarized light over a broad bandwidth up to 50 terahertz in the near-infrared region. A simple and intuitive working principle based on the symmetry inherent in the metamaterial design i...
