Feasibility Study of THz Multiplexer and Demultiplexer Employing Arrayed Waveguide Gratings

摘要

We propose the feasible design of a device that can offer a unique method for controlling the terahertz spectrum allocation,exploiting existing photonics-based technologies. We successfully designed a multiplexer and demultiplexer using arrayedwaveguide grating, where the device can multiplex and demultiplex four frequency channels (8.64 GHz bandwidth) in thesame operating range defined by the IEEE 802.15.3d standard with at least 10 dB separation. This study reveals thatproposed solution play a major role in maturing the next generation wireless communication (beyond 100 GHz) networks.
