However, such multiplexing properties have been mostly passive or transient thus far and have not been used to deliver active modulators or reconfigurable elements in optical systems. Polarization, one of the fundamental properties of electromagnetic waves, provides extra physical dimensions for multiplexing optical information, enabling applications such as multidimensional spectroscopy ( 1), high-capacity communication ( 2– 4), ultrafast detection/modulation ( 5, 6), polarization-controlled holography ( 7), and others ( 8, 9). While our HAD nanowires use phase-change materials as the active material, this concept is readily generalized to other active materials hybridized with dielectrics and thus has the potential in a broad range of applications from photonic memories and routing to polarization-multiplexed computing. By using polarization as the tunable vector, we show matrix-vector multiplication in a nanowire device configuration. We then demonstrate the ability to use polarization as a parameter to selectively modulate the conductance of individual nanowires within a multi-nanowire system. Here, we introduce hybridized-active-dielectric (HAD) nanowires to achieve polarization-selective tunability. While wavelength-selective systems have widely proliferated, polarization-addressable active photonics has not seen notable progress, primarily because tunable and polarization-selective nanostructures have been elusive. The second is by vectorizing a bitmap image.Wavelength and polarization are two fundamental properties of light within which information can be encoded and (de)multiplexed.

There are two ways to create a vector image - the first is creating it from scratch within the software by designing something. Examples include GIMP and CorelDRAW, used by graphic design enthusiasts and professionals alike. So how do you create a vector image? Well, there are plenty of different types of vector software out there to use. If you tried this with a bitmap image you would get a very blurry result. Vector images are ideally suited for logos which may be blown up into print, for instance on clothing, car wraps, billboards, magazines, bus station ads - anything which requires the image to be scaled up a large amount. They can easily be edited and manipulated to change colors, shapes, and text, making them a go-to tool for graphic design. No matter the size of the image, it will not become blurry or pixelated like a bitmap image. The main benefit of a vector image is that it is instantly scalable with pristine resolution. Examples of raster image files are JPEGs, PNGs, and GIFs.

Images tend to be flat, using line art and uniform colors, and are generally found when working with logos, letterheads, and fonts.Įxamples of vector files are SVG, EPS, AI, and PDF files. Vector images are based on mathematical formulas that define geometry such as lines, curves, circles, rectangles, and other clear bold shapes. CorelCAD 2023 – Education Edition (Windows/Mac).
