Ueno Lab
Machine-translated · View original
An optoelectronics lab that manipulates optical signals at high speed while keeping them as light.
AboutAbout the lab
Directly manipulating optical signals with ultrafast optical signals.
The Ueno Lab studies ultrafast information and communication technology that manipulates optical signals while keeping them as light.
Using its own original approaches, the lab studies new optical materials, devices, and circuits, aiming to handle high-speed optical signals at 200 gigabits per second.
Its research fields are ultrafast optoelectronics, quantum electronics, optical signal processing, and optical frequency combs.
The lab also works on optical logic gates, which serve as an "optical transistor" to replace the electronic transistor.
Key terms
- Optical transistor
- A device that performs gate operations directly on optical signals, in place of an electronic transistor. Also called optical logic.
- Optical signal processing
- Processing optical signals at high speed as light, without converting them into electrical signals.
- Optical frequency comb
- Light whose frequencies are evenly spaced, giving a spectrum like the teeth of a comb.
ResearchResearch themes
The lab studies optical materials, devices, and circuits for processing optical signals at high speed without converting them into electrical signals. Examples of its research include optical semiconductor materials, optical logic gate circuits, optical pulse generation circuits, and high-speed, high-precision measurement technology (the lab page's content dates from around 2014).
