“…The radius of the rod is r = 125 nm. Figure 3(a) shows the magnetic (H) field intensity pattern of the transverse electric (with the H field along the y direction) mode at wavelength l = 480 nm, which is calculated by the multiple scattering theory [14,15]. The incident wave vector is marked by the white arrow.…”

We report on-chip structures based on ordered dielectric nano-particle chain which can be used to steer and tune optical beams. With different elaborately designed structures, the optical beam can transmit in a negative direction, or totally reflected beyond the normal incidence with a subwavelength nanorod chain. The mechanism of the phenomenon is believed to be due to the symmetry of resonant modes in the dielectric nanoparticles. With the low-loss feature and the ultra-compact characteristic, this structure may find applications in photonic circuits.

“…The reflectivity of the circular rod structure is calculated by using multiple scattering theory. 14,18 The high reflectivity is believed to be due to the same underlying physics. Since both types of structure work well, we can choose a circular or square cross-section for convenience in practical applications.…”

Abstract. We report a polarization-dependent reflector beyond normal incidence with a subwavelength nanoparticle chain. Polarization-dependent reflection with high reflectivity or high transmissivity can be obtained with this structure. Light waves of transverse electric/magnetic mode will be reflected, while the transverse magnetic/electric mode will transmit through. The structure shows a certain degree of tolerance of incident angle, technical fabrication, and even particle shape. We hope the lowloss and compact structure can find applications in photonic circuits such as gallium nitride-based light sources. © The Authors.

A thin‐film photonic lens is fabricated using chirped plasmonic grating structures, which enables off‐axis focusing and simultaneous de‐multiplexing of the incident light beams, as well as the intrinsic function of an optical lens for imaging. This planar two‐dimensional photonic device may be used either as a positive (converging) or a negative (diverging) lens through controlling how the light beam is incident and how the device is oriented, which defines multifold ‘diode’ effects and is thus termed “forward” or “backward” biasing of such a ‘diode’ lens. This plasmonic photonic diode (PPD) features by unidirectional functions instead of non‐reciprocal transmission. These unique functions are demonstrated by focusing different colors into different angles and different focal lengths with large dispersions, which enables direct wavelength division de‐multiplexing with high resolution and high efficiency. Strong plasmonic scattering by the gold nanolines that constitute the chirped grating structures leads to efficient operation and polarization‐dependent performance of the PPD device.
