The natural progression towards the next generation high-speed wireless communication system is going into the regime of Terahertz spectrum. There is a need to develop a platform that could manipulate Terahertz waves seamlessly and to provide a building block for the next generation wireless communication system that will support a fast and reliable wireless data transfer while providing a compact design for commercialisation. In this project, integrated photonic devices based on photonic crystal structure is designed systematically to enable a fast and reliable wireless data transfer operating in low Terahertz frequency spectrum (300-350GHz). The design is done on COMSOL Multiphysics and CST Microwave Studio. The designed devices have achieved a wide bandwidth performance (~10GHz) that will enable ultra-fast data transfer rate up to the order of Gbit/s. The topological counterpart has also been designed and is proven to be immune against reflection loss. This will consequently enable a defect-insensitive device robust against manufacturing imperfection and improve the reliability of the device. The integrated photonic devices based on photonic crystal structure will inevitably become the backbone of the future wireless communication system and will pave the way to the novel 6G communication system.
