A Galerkin’s method-based numerical procedure is extended to obtain the modal field distribution of multicore photonic crystal fibers for the first time to our knowledge, which can reveal how the air hole size influences the mode coupling and how the coup
An InP-based monolithically integrated few-mode transmitter aiming at the combination of wavelength division multiplexing (WDM) and mode division multiplexing (MDM) technologies is proposed. The core elements of the proposed transmitter are mode converter
气动激光器自从两年前第一次公开发表以来已经走了一段长的路程。目前器件的特征是较高的容器温度与压力、较小的喷嘴喉部高度、较大的面积比和较大的含水量。应 用了新的气体和激射跃迁,如麦肯齐(R. L. McKenzie)对CO-N2-Ar混合气体的工作和格鲁兹臻斯基(G. Gruszczynski)对 Ar -He 工作。
