25.8Gbps Direct Modulation AlGaInAs DFB lasers with Ru-doped InP Buried Heterostructure for 70°C operation
25.8Gbps Direct Modulation AlGaInAs DFB lasers with Ru-doped InP Buried Heterostructure were fabricated for the first time. The lasers achieved high output power and clear eye opening at 70°C and are promising for uncooled operation.
High-speed modulation lasers for 100GbE applications
We describe the performance of 1.3-µm InGaAlAs RWG-MQW-DFB lasers and EA-DFB lasers applicable to 40G/100G Ethernet. We obtained a 3-dB-down bandwidth frequency of over 30 GHz and clear eye opening at a 40-Gb/s modulation speed.
Natural history and long‐term evolution in families with autosomal dominant cortical tremor, myoclonus, and epilepsy
Purpose:  To investigate for the first time the natural history and long‐term evolution of “familial cortical tremor, myoclonus, and epilepsy.”
