| Abstract: | To solve the frequency stability and accuracy of THz wireless communication carrier,it proposed one new method which based on the optical frequency multiplier.The multiplier is composed of optical comb signal generator,optical tunable filters,and UTC-PD optical mixer.The two-mode coherent light signal is generated by multiplying optical comb signal and the adjustable optical fiber,and then it goes to UTC-PD for optical heterodyne mixer and finally to generate THz carrier of high frequency and high saturation output power.It also evaluates the linewidth,single side-band phase noise and spurious signal suppression ratio. |
