Design of Ultra-wide Bandwidth Electro-optic Modulation Chip Parameter Testing System(Invited)
Frequency domain parameters such as bandwidth and response flatness of electro-optical modulator chip are important evaluation indexes to measure the performance of electro-optical modulator chip.The frequency domain parameter testing method of electro-optical modulator chip is studied,and a frequency response parameter testing system of electro-optical modulator chip based on ultra-wide bandwidth lightwave component analyzer is es-tablished.The core frequency response parameters of the electro-optical modulator chip are tested in the range of 10 MHz～110 GHz.Experimental results show that the measurement results of the proposed method are in good agreement with the simulation results,and it is an efficient and high-precision method for testing the frequency re-sponse parameters of the electro-optical modulator chip.
