Abstract
This invention discloses an integrated module for the transmitter of a photonic terahertz wireless communication system. The integrated module includes: an optical signal emitted by a tunable laser chip, which is focused by a focusing module and then enters a modulation coupler chip through its signal input terminal; a modulation driver chip, which sends a modulation drive signal to the modulation coupler chip to control its operating state; and a signal output terminal of the modulation coupler chip coupled to the signal receiving terminal of an antenna photodiode chip. The modulation coupler chip modulates the received optical signal according to the modulation drive signal to generate a modulated optical signal, and transmits the modulated optical signal to the antenna photodiode chip through its signal output terminal. The antenna photodiode chip converts the received modulated optical signal into an electromagnetic wave signal and radiates the electromagnetic wave signal into free space. This invention features high integration, low energy consumption, and more flexible application scenarios.
