We report on a lumped-EML submodule with 3-dB bandwidths of 68.2 GHz at 25℃ and ~66 GHz at 70℃ using a resistance-optimized LC resonance effect, showing low temperature dependence and making it suitable for 112-Gbaud operation.

We have fabricated DML/EML-based subassembly modules based on chip-to-chip optical butt-coupling with straight waveguides between a silica AWG chip and commercial directly modulated laser (DML) or electro-absorption modulated laser (EML) chips. By pr

By using LC resonance effect with optimization of load resistance, the 3-dB bandwidth of a lumped-EML submodule can be enhanced to > 55 GHz although an EAM length is 150 um, making it enable 100-Gbaud operations.

Using an optical butt-coupling method, we have developed a low-cost hybrid-integrated 4×100G TROSA module, showing clear Tx optical eye patterns and Rx sensitivities within −7.0 ~ −6.4 dBm at 106-0bps PAM4 signals for all channels.

By external optical feedback effect on DMLs butt-coupled with a silica-based AWG, we present that 3-dB bandwidths of a DML submodule can be extended to ~37.5 GHz (@ 90 mA) using commercial 28-Gbaud DML chips.

We present mutual interference problems in the frequency-modulated continuous-wave (FMCW) LiDAR. There are two types of the mutual interference, the transient interference, and the in-band interference. We show that the former case induces degradatio

This paper investigates mutual interferences between FMCW LiDARs both experimentally and theoretically. We show that the FMCW LiDARs have mutual interference problems as those of the FMCW radars. The transient interference degrades the signal-to-nois
