Abstract :
A traveling wave electro-absorption modulator (TWEAM) module for 60 GHz band radio-over fiber link was developed. The fractional bandwidth at the operating frequency can be controlled with the termination resistance and it was shown that to estimate the fractional bandwidth, the model should contain the effect of packaging parasitics. Impedance matching in the module was achieved with the double stub design and the laser trimming process. The measured electrical-to-optical (E/O) response showed the increased in the response near 60 GHz. In addition, a filter as an implement of the impedance matching was proven to be an effective solution.
