Serial Arrayed Waveguide Grating

Dispersive optical elements are important for many applications. In bulk, free-space optics, prisms, and gratings are often used. In optical waveguides, particularly in integrated photonics, arrayed waveguide gratings (AWG) are most commonly used. AWGs split an optical signal into different wavelength channels. Serial Arrayed Waveguide Grating enables higher resolution wavelength separation.
