As a key device for the application of terahertz waves (with frequencies in the region between radio and light waves), we focus on the development of a compact resonant tunneling diode, which can oscillate at the highest frequency among various simple electronic devices. The purpose of this research is to purse the maximum transmission rate using a terahertz resonant tunneling diode for wireless communication applications. In order to overcome the transmission rate limitation using a simple resonant tunneling diode, we create a novel integrated technology to develop ultrahigh-speed wireless communication systems with low power consumption using terahertz waves through the fusion of resonant tunneling diodes and photonic crystals, which can be used as an ultralow-loss terahertz integration platform.
