Abstract

In this work, we demonstrate for the first time to our knowledge, a green light wavelength demultiplexer device, based on multi Slot waveguide (SW) structures. Gallium Nitride (GaN) surrounding Silica (SiO²) were chosen for confining the light inside the SW region and found to be suitable for operation within the visible light spectrum. The proposed device as well as his geometry, aims and optimized to demultiplex wavelength in the green light range with wavelengths of 500, 510, 520 and 530 nm. The device is composed of six SW units and six S-bands (SB). A full vectorial beam propagation method (FV-BPM) and coupling mode theory used to study and analyze the demultiplexer device. The proposed device obtains losses better than 0.1275 dB, crosstalk as well as -21.135 dB and full width at half maximum (FWHM) smaller than 9.5 nm, in an overall compact size of only 104 μm. The proposed device has the ability to increase the data bit rate in visible light communication (VLC) system that works with wavelength division multiplexing (WDM) technology.
