Spin lasers could push data into the fast lane
BOCHUM, Germany – A new concept for ultrafast semiconductor lasers uses the intrinsic angular momentum of electrons – also known as spin – to break previous speed barriers, with the potential to achieve modulation frequencies of well above 100 GHz. The results could be a significant step toward high-speed data transmission for the Internet of the future. Researchers at Ruhr University Bochum were inspired by spintronics – combining quantum mechanical spin with semiconductor-based electronics ...
NeoPhotonics: Q3 Results 'Disappointing'
SAN JOSE, Calif., Nov. 14, 2011 — Lower demand from its largest customer and acquisition-related costs were the biggest factors behind a third-quarter loss of $4.1 million, photonic integrated circuit maker NeoPhotonics reported last week. The company also cautioned that the...
Spin Lasers in the Fast Lane
BOCHUM, Germany, Nov. 4, 2011 — A new concept for ultrafast semiconductor lasers makes inventive use of the intrinsic angular momentum of electrons, called spin, to break previous speed barriers. The new spin lasers have the potential to achieve modulation frequencies of...
Mini Lasers Could Help Launch New Internet Age
ORLANDO, Fla., March 21, 2011 — A miniature laser diode has been created that emits intense light at a single wavelength, making it ideal for high-speed data transmission. Until now, the biggest challenge has been the failure rate of these tiny devices. They don't work very...
Fiber Optic Connectors: Meeting Polishing Demands
Nov 1, 2003 — Optical fiber is a good vehicle for high-speed data transmission as long as light transmission is efficient — even across connector assemblies. This translates to a need to polish connector end faces to optimize performance. Increasingly, with the...
