Abstract :
This paper presents a small quad-channel driver module for optical modulators in digital coherent systems. To decrease the size of the module, we designed a compact quad-channel package. The size of the package is 14 × 8 × 2.8 mm3. The bandwidth of the driver module is 36 GHz with maximum differential gain of 15 dB. Waveforms with clear eye-openings at symbol rates of 32 and 50 Gbaud were observed. To the best of our knowledge, this is the most compact quad-channel driver module in 50-Gbaud class.
