Amplitude Modulator

The Terahertz modulator based on polymer electro-optic modulation is designed by Macher-Zehnder structure. The ridge waveguide is used to realize TM00 mode transmission, and the Y-branch with double circular arch type is to decrease the loss of transmission in modulator. The transmission of THz is analyzed by the beam propagate method (BPM). The structure parameters of the M-Z modulator, such as the size of ridge waveguide, the type of Y-branch and the optical offset structure for phase, are optimized to realize THz amplitude modulation. The depth of modulation is 83.8% when the applied field is 31.5V.
