We fabricated a flip-chip interconnection lumped-electrode EADFB laser module and an optical receiver that includes a broadband electrical amplifier. Both have a 3-dB bandwidth of more than 50 GHz. Under 53.2-Gbaud 4-PAM (107 Gb/s) operation, clear e

We have developed a flip-chip interconnection technique to solve the problem of the degradation of the modulation bandwidth of an optical transmitter due to the parasitic inductance of bonding wire. And we have fabricated an LE-EA-DFB laser module th

The influence of impact-ionized holes accumulating in the device was studied for InP-based InAlAs/InGaAs HEMTs using light irradiation experiments. Two parasitic phenomena arise from the generation of electron-hole pairs and subsequent accumulation o
