چکیده انگلیسی
A novel technique and related formulations are proposed for analyzing the influences of the skin-effect on the performances of a polymer Y-fed coupler electro-optic modulator with shielded push-pull micro-strip electrodes. Using the extended point-matching method, coupled mode theory and electro-optic modulation theory, thorough design and optimization are performed. By introducing the effective applied voltage, formulas of the high-frequency response under skin-effect are deduced, and characteristics under skin-effect are analyzed. Under the central wavelength of 1550Â nm, the half-wave voltage is as low as 1.097Â V for the device with an active region length about 8.884Â mm. Considering the influences of the skin-effect, the 3-dB modulating bandwidth of the microwave signal is up to 94Â GHz. A high extinction ratio of more than 20Â dB and a low insertion loss of less than 4.18Â dB are achieved when the microwave frequency is below 68Â GHz under skin-effect. This design technique is proven to be accurate by the comparison with the beam propagation method (BPM).
