摘要：This paper presents a generation of terahertz(THz)signal with photonic system using microringresonator and direct modulated laser. DM laser is given as input to microring resonator. The output signal obtained from the photodetector consists of full-width half maximum(FWHM) is higher when comparing to the MLL. Also the parameters of BER and Q-factors are investigated.Thus the THz signal produced seems to be more efficient. Hence the proposed microwave photonic system generates THz carriers which can be efficiently used for communication between a pico/femto cell base station and the mobile user or between two devices present in the same pico/femto cell or different cells deployed in a macro cell of a 5G environment.
