Cost-efficient contention resolution is an urgent topic in Optical Burst Switching. This paper examines the performance of a core OBS node equipped only with partial wavelength conversion, and investigates how the choice of burst scheduling algorithm can affect its blocking rate performance and converter usage. In particular, sensitivity of performance is examined with respect to burst length. ...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

Wavelength conversion based on the cross-polarization modulation (XPM) in a single semiconductor optical amplifier (SOA) has been numerically investigated by using the theoretical model in which the birefringence has been taken into account. The results show that the non-inverted and inverted wavelength conversion can be realized through selecting reasonably the parameters; there exit some diff...

This work assesses the prospects for high-speed alloptical wavelength conversion using the simple optical interaction with the gain in semiconductor optical amplifiers (SOA’s) via the interband carrier recombination. Operation and design guidelines for conversion speeds above 10 Gb/s are described and the various tradeoffs are discussed. Experiments at bit rates up to 40 Gb/s are presented for ...

We present an integrated optical isolator based on adiabatic wavelength conversion in microcavities. The isolator uses a time-division sampling method to ensure complete isolation of optical pulses with an extinction of 24 dB. ©2009 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (230.3240) Isolators.

We report multifunctional integrated photonic switches that provide optical wavelength conversion across the C-band at 3.5 Gb/s that is electrically packet-switched within a reconfiguration time of <2.5ns. These switches also provide optical packet-switching in <300ps. © 2005 Optical Society of America OCIS codes: (250.3140) Integrated optoelectronic circuits; (060.2330) Fiber optics communicat...

waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. optical fibers can also be employed in such systems. besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. in this paper, we introduce two new designs of index-guiding photonic crystal fiber ...

We propose and demonstrate an all-optical sub-carrier label-swapping subsystem with 2R regeneration and wavelength conversion. The experimental results show error-free operation as well as regenerating operation with negative power penalty. 2003 Optical Society of America OCIS codes: 060.2330 Fiber optics communications, 060.4510 Optical communications
