摘要： The present invention provides devices and methods for dispersion compensation. According to one embodiment of the invention, a dispersion compensating device includes a negative dispersion fiber having an input configured to receive the optical signal, the negative dispersion fiber having a length and dispersion sufficient to remove any positive chirp from each wavelength channel of the optical signal, thereby outputting a negatively chirped optical signal; an amplifying device configured to amplify the negatively chirped optical signal; and a nonlinear positive dispersion fiber configured to receive the negatively chirped optical signal. The devices of the present invention provide broadband compensation for a systems having a wide range of variable residual dispersions.

摘要： An optical channel shared protection ring (20) including multiple ring nodes (102, 104, 106, 108), the nodes including optical switch or crossbar capability for performing ring switching for end-node protection switching for wavelengths that may be dropped and added and a non-intrusive optical channel monitor (22, 62) at least on each working channel both on the add and drop side of the node, such that a monitor is always present at both a head-end location where traffic is introduced to the ring and at a tail end location where traffic leaves the ring, so as to be able to trigger end-node protection switching performed by the head-end and tail-end nodes based on the condition of absence of adequate signal at both the head-end and the tail-end location, thus avoiding unnecessary protection switching.
摘要翻译：包括多个环形节点（102,104,106,108）的光学信道共享保护环（20），所述节点包括用于对可以被丢弃和添加的波长进行端点保护切换的光交换机或交叉网络能力，以及至少在节点的添加和丢弃侧上的每个工作通道上的非侵入式光通道监视器（22,62），使得监视器总是存在于头部位置处，其中业务被引入环并且在流量离开环的尾端位置处，以便能够基于在前端的两端没有足够的信号的条件来触发由前端节点和尾端节点执行的端节点保护切换和尾端位置，从而避免不必要的保护切换。

摘要： Methods, systems, and devices for non-invasive measurement of cell cultures are described that provide for remote monitoring of cell status. The system includes a cell culture vessel, at least one monitoring layer, at least one measurement device, and a communication component. The cell culture vessel may include at least one cell culture chamber configured for cell growth and for closed-system operation. The monitoring layer is external to the at least one cell culture chamber. In some cases, the communication component is configured to transmit data from the monitoring layer to a remote location.

摘要： Disclosed is a single made optical waveguide fiber having a segmented core design. In particular, the core comprises three segments, each having characteristic dimensions and refractive index profile. By proper choice of index profile in each segment, a waveguide fiber is made which has a mode field diameter of about 9.5, low, positive total dispersion over the operating window 1530 nm to 1565 nm as well as effective area greater than 60 mum 2 .

摘要： A single mode optical waveguide fiber having a refractive index profile comprising not less than four segments (16, 18, 20, 22) provides waveguide properties well suited to undersea or other long haul telecommunications systems. The novel refractive index profile is characterized by a core segment having a negative relative index, in which, the reference index is that of silica. Another feature of the invention is a cladding layer which contains refractive index increasing dopant at least in the cladding portion adjacent the outermost core segment.
