A novel low cost bidirectional transmission coherent passive optical network system
Published 2016-07-01“…Based on the coherent optical reception technology,a cost-effective structure for the optical network unit (ONU) transceivers in ultra-dense wavelength division multiplexing passive optical network using a single directly modulated laser (DML)was proposed.To reduce the number of required light sources,only one DML was used in both upstream and downstream links.By experimental investigations,the impacts of driving amplitude and bias current on DML's performance were analyzed.Meanwhile,the impact of frequency spacing between upstream and downstream signal and the Rayleigh backscattering interference on system performance were investigated.The method has better performance of system receiving and can effectively reduce the cost and complexity of coherent passive optical network system.…”

Novel shortcut strategies in copositivity detection: Decomposition for quicker positive certificates
Published 2025-06-01“…In this paper, we present novel promising shortcut strategies to exploit favorable instances in a systematic way, using decomposition strategies based upon the idea to allow for overlapping, smaller blocks, profiting from a beneficial sign structure of the entries of the given matrix. The working hypothesis of this approach is the common empirical observation in the community that for detection of copositivity, a negative certificate is easier to obtain than a positive one. …”
