New Design of Grating Couplers with Fiber Optics for Use as Combined Power Divider and Wavelength Demultiplexer

Open Access Open Access

Abstract

Digital phase gratings were formerly investigated by a simple Fourier transformation to optimize their behavior, e.g., distributing the incident radiation in distinct spectral bands to specific diffraction orders or distributing the incident intensity of light into equally bright central orders.
