WebA superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit. For example, in 1995, Guerra [1] combined a transparent grating having 50nm lines and spaces (the "metamaterial") with a conventional microscope immersion objective. The resulting "superlens" resolved a silicon sample also having 50nm lines and ...

Web1 Sep 2024 · Subwavelength grating structures reduce the index contrast, thereby smoothing the transition between the waveguides and the intersection zone and … WebExploiting new wavebands became a crucial problem within the optical communications community. The 2 μm spectral range between near-infrared and mid-infrared held advantages of low transmission loss and broad gain bandwidth, which made it a promising candidate for the next window of free space laser and optical fiber communications.
Web24 Jul 2024 · The SWGS waveguide is characterized by the merging of a slot structure and a subwavelength grating (SWG) structure. The mode guiding mechanism (SWG slot mode) … WebSWGs offer high reflectivity for a broad spectral region with significant phase changes; this property can be used to engineer the beam. As shown in Fig. 1, the SWG grating is a set of silicon grooves with period=0.76um on a quartz substrate. It is illuminated at normal incident with a TM–polarized plane wave.
