A thermoelectric (TE) device using cutting edge thermoelectric conversion technology has been created by a team comprising NEC Corporation, NEC TOKIN Corporation and Tohoku University. The new technology, known as the spin Seebeck effect, has conversion efficiency 10 times higher than the conventional method. Thermoelectric conversion technology that converts energy abandoned as waste heat back to…
New Heterogeneous Wavelength Tunable Laser Diode for High-Frequency Efficiency
Researchers at Tohoku University and the National Institute of Information and Communications Technology (NICT) in Japan, have developed a novel ultra-compact heterogeneous wavelength tunable laser diode. The heterogeneous laser diode was realized through a combination of silicon photonics and quantum-dot (QD) technology, and demonstrates a wide-range tuning-operation. The researchers presented their work at a Conference…
