Investigation of a fiber-optic polarizer with a metal film and a dielectric buffer layer
Soviet Journal of Quantum Electronics, 1990A model of a plane-layer waveguide is used in a theoretical analysis of the attenuation coefficients of the TM0 and TE0 waves in a fiber-optic polarizer with a metal film and two dielectric buffer layers, one of which is the residual part of the fiber cladding.

Shared fiber delay line buffers in asynchronous optical packet switches
IEEE Journal on Selected Areas in Communications, 2006Packet contention is a major issue in asynchronous optical packet switching networks. Optical buffering, which is implemented by fiber delay lines (FDLs), is fundamental to many optical switch implementations for resolving contention. Most existing optical buffering implementations are output-based and require a huge amount of FDLs as well as larger ...

Development of optical indoor cables using 0.9-mm tight-buffered optical fiber
2009 14th OptoElectronics and Communications Conference, 2009We propose optical indoor cables using 0.9-mm tight-buffered optical fiber, placing importance on handling performance and ease of work. This MM fiber-based cable allows 10-Gbps transmission for up to 600 m.

IEEE Journal on Selected Areas in Communications, 2006
We study optical fiber-delay-line buffer management schemes for supporting service differentiation with less complexity, with the objective of achieving ultra-high-speed packet forwarding in a photonic packet switch. We propose the vPBSO (Variable-length-packet-capable Partial Buffer Sharing with Overwriting) method, which is a prioritized buffer ...

Gallium-arsenide buffer store components for Gbit/s optical-fiber transmission systems
IEEE Journal of Solid-State Circuits, 1989In many cases long-haul optical-fiber transmission systems require the use of buffer stores to interface to a larger network, for example, to reduce the effects of jitter accumulation. A set of gallium-arsenide (GaAs) buffer-store components designed and manufactured using a 1- mu m process is described.

Investigation of bare and tight-buffered optical fibers towards distributed humidity sensing
Seventh European Workshop on Optical Fibre Sensors, 2019Humidity is one of principal environmental parameters that plays an important role in various application areas. Using measurement of strain induced in an optical fiber by a water swellable coating represents a promising approach for realization of distributed humidity sensing (DHS).

All-optical loadable and erasable storage buffer based on parametric nonlinearity in fiber
Journal of Lightwave Technology, 2005We present a loadable and erasable all-optical fiber storage buffer based on parametric gain and cross-phase modulation (XPM) loading. The gain is provided by a phase-sensitive amplifier (PSA), implemented as a Sagnac interferometer, and relies on the nonlinear interaction within standard dispersion-shifted fiber.

Variable Delay Optical Buffer Using Tunable Fiber Bragg Gratings
2014A novel all-optical variable delay buffer for next generation optical networks is reported. This buffer can store the contending packets for a relatively long time by using fiber Bragg gratings (FBGs). The proposed design is characterized by the ability to extract the delayed packets as soon as the contention is resolved.

Analysis of VAS, WAS and XAS Scheduling Algorithms for Fiber-Loop Optical Buffers
2018In optical packet/burst switched networks fiber loops provide a viable and compact means of contention resolution. For fixed size packets it is known that a basic void-avoiding schedule (VAS) can vastly outperform a more classical pre-reservation algorithm as FCFS.
