Polarization independent demultiplexing in a polarization diversity nonlinear optical loop mirror
IEEE Photonics Technology Letters, 1997Polarization independence is a prerequisite if all-optical demultiplexing is to be implemented in future high-speed communication links. The nonlinear optical loop mirror (NOLM) switch has shown potential to work at very high speed. Polarization-independent switching in the NOLM has previously been reported using cross-spliced polarization-maintaining ...

Soliton squeezing in a highly transmissive nonlinear optical loop mirror:?errata
Optics Letters, 1999A perturbation approach is used to study the quantum noise of optical solitons in an asymmetric fiber Sagnac interferometer (a highly transmissive nonlinear optical loop mirror). Analytical expressions for the three second-order quadrature correlators are derived and used to predict the amount of detectable amplitude squeezing along with the optimum ...

Polarization-insensitive nonlinear optical loop mirror demultiplexer with twisted fiber
Optics Letters, 1999We experimentally demonstrate reduction of the polarization sensitivity of a nonlinear optical loop mirror (NOLM) from 5 to 0.5 dB by use of 550 m of twisted dispersion-shifted fiber with a twist rate of 8 turns/m (24 turns/beat length). The twisting of the fiber induces circular birefringence and equates the parallel-and the orthogonal-polarization ...

Dual-control nonlinear-optical loop mirrors for all-optical soliton synchronous modulation
Optics Letters, 1996A novel dual-control configuration of nonlinear loop mirrors is used for all-optical soliton synchronous regeneration. Simulations show substantial improvement in transmission in this device compared with singlecontrol devices, owing to chirp-free modulation.

A novel all-optical demultiplexing scheme based on the fiber nonlinear optical loop mirror
Conference on Lasers and Electro-Optics-Europe, 1998The fiber nonlinear optical loop mirror (NOLM) is widely used in the OTDM demultiplexing, because it has the potential of operation at the extreme high bit rates. For traditional NOLM (only one control beam), however, timing jitter between the clock and the signal and crosstalk mainly arising from the unwanted cross-phase-modulation (XPM) in the ...

Impact of fiber birefringence on optical switching with nonlinear optical loop mirrors
IEEE Journal of Selected Topics in Quantum Electronics, 2004We use a vector theory of cross-phase modulation to discuss how residual birefringence of the fiber loop affects the switching performance of a nonlinear optical loop mirror. It is found that the interaction between polarization-mode dispersion (PMD) and cross-phase modulation transfers spatial randomness of residual birefringence to temporal power ...

Amplitude modulation using a nonlinear optical loop mirror
2012The nonlinear optical loop mirror (NOLM) configuration has been studied extensively within the context of pulsed and/or quasi-CW laser sources. As such, the NOLM holds great promise in the areas of soliton switching, pulse compression and high data rate communications. However, comparatively little research has been done with CW sources.
