“…However, it is difficult to realize the spot below diffraction limit due to the optical diffraction limit effect. In order to break through the diffraction limit, lots of ways to obtain super-resolution non-diffraction beam were presented and discussed such as hyperlens and super-oscillatory lens [9][10][11], utilizing superlens to turn evanescent waves into propagating waves and obtain subwavelength imaging [12,13], handling of the evanescent waves with near field diffraction structures [2,14], and super-resolution apodization through pupil masks [14][15][16][17][18]. In these methods, the superresolution pupil filters (or phase plates) with amplitude and phase modulations are always hot subjects.…”

“…According to our experience, the super-resolution and depth of focus (DOF) extension effects are good for phase plate with central block, but the drawback is that much energy is blocked. In addition, most of them used radially polarized beam as incident light to conduct subsurface imaging, which is difficult to apply in optical data storage and photolithography due to the deterioration of resolution for a longitudinally polarized beam inside materials [2,18]. To overcome this drawback, Grosjean et al [1] proposed a type of material that is sensitive only to the longitudinal component.…”

Abstract-In order to obtain a super-resolution non-diffraction beam, we propose a fast searching method to design a ternary optical element combined with the circularly polarized light. The optimized results show that a beam with a spot size of 0.356λ and depth of focus of 8.28λ can be achieved by focusing with an oil lens of numerical aperture N A = 1.4 and refractive index of oil n = 1.5. The analysis reveals that the spot size of transverse component is 0.273λ, indicating that the super-resolution effect mainly comes from the transverse component. The spot size inside the media can theoretically reach down to 0.273λ because the spot size inside the media is mainly determined by the transverse component.

Abstract:Recently there is an increasing interest in complex optical fields with spatially inhomogeneous state of polarizations and optical singularities. Novel effects and phenomena have been predicted and observed for light beams with these unconventional states. Nanostructured metallic thin film offers unique opportunities to generate, manipulate and detect these novel fields. Strong interactions between nano-metallic surfaces and complex optical fields enable the development of highly compact and versatile functional devices and systems. In this review, we first briefly summarize the recent developments in complex optical fields. Various nano-metallic surface designs that can produce and manipulate complex optical fields with tailored characteristics in the optical far field will be presented. Nano-metallic surfaces are also proven to be very effective for receiving and detection of complex optical fields in the near field. Advances made in this nascent field may enable the design of novel photonic devices and systems for a variety of applications such as quantum optical information processing and integrated photonic circuits.

The van der Waals heterojunctions of 2D materials offer tremendous opportunities in designing and investigating multifunctional and high-performance electronic and optoelectronic devices. In this study, a vertical p-n diode is constructed by vertically stacking p-type few-layer black phosphorus (BP) on n-type few-layer indium selenide (InSe). The photodetector based on the heterojunction displays a broadband and gate-modulated photoresponse under illumination. More importantly, by taking advantage of the strong linear dichroism of BP, the device demonstrates a highly polarization-sensitive photocurrent with an anisotropy ratio as high as 0.83. Additionally, the device can function in a zero-bias photovoltaic mode, enabling a fast photoresponse and low dark current. The external quantum efficiency can reach ≈3%, which is impressive for BP-based devices. The results pave the way for the implementation of p-BP/n-InSe heterostructure as a promising candidate for future multifunctional optoelectronics and, especially, polarization-sensitive applications.
