Abstract :
TWEAM modulator modules optimized in 40 GHz and 60 GHz band, respectively, were developed. The bandwidth at the operating frequency can be controlled with the termination resistance. Impedance matching of the modules was achieved using the double stub design and the laser trimming process. The measured Electrical-to-optical (E/O) response showed the increase in the response near 40 GHz and 60 GHz, respectively. The third-order inter-modulation distortion (IMD3) was below -65 dBc at -7 dBm RF input and spurious free dynamic range (SDRF) was about 108 dB Hz23/.
