We newly propose and experimentally investigate an InGaAs-channel high-electron-mobility transistor integrated with a unitraveling-carrier photodiode (UTC-PD) structure on its source side for an ef…
We describe the first on-line 256 QAM digital coherent optical transmission system with an ECLD light source and DFB LD-based injection-locking, and an FPGA-based transceiver. In this system, preci…
