Hank Hogan, Contributing Editor, [email protected] To take communications to the next level, laser technologies must improve in terms of cost, efficiency and robustness. Fortunately, those improvements are in the works. Whether traveling through free space or over a fiber, lasers power data delivery – so laser innovations can up data rates, cut costs and improve capabilities. Arguably, the greatest need for better communications lies in data centers, the conglomeration of computers and storage that make the online world go. Networking giant Cisco predicted in October 2013 that global data center traffic would triple between...Read full articleRelated content from Photonics MediaArticlesQuantum-Dot Laser Elevates Efficacy of Frequency Combs for PICsUniversity of California, Santa Barbara (UCSB) researchers led by John Bowers have developed a quantum-dot (QD) mode-locked laser that allows amplitude-modulated (AM) and frequency-modulated (FM)...Photonics Spectra October 2023 IssueIntegrated Photonic Quantum Sensing Takes Aim at Climate ResearchA NASA-funded collaboration will focus on advancing quantum sensing technology to enable new understanding of Earth and the effects of climate change.
