Stephanie A. Weiss

In standard communications math, 40 lasers + 40 modulators + one fiber = 40 channels of dense wavelength division multiplexing. In Lucent Technologies' new math, one laser + one modulator + one fiber = 1022 channels of ultradense wavelength division multiplexing. Scientists at Lucent Technologies' Bell Labs announced the record wavelength density in November to highlight the enormous potential of femtosecond laser technology in communications. The demonstration extends a 1997 experiment that transmitted 206 wavelengths on one fiber, and Wayne Knox, head of Bell Labs' Advanced Photonics...Read full article
