Large bandwidth TO-CAN module with LCP based transmission line as serial 40 Gb/s 1.3/1.55-µm light source

We developed 40-Gb/s 1.3/1.55-µm TO-CAN modules based on an electroabsorption modulator integrated with DFB lasers (EMLs). We obtained clear eye openings and an electrical to optical 3 dB-down bandwidth of 33 GHz.
