In the previous chapter, we discussed devices based on deliberately introduced birefringence in an optical fiber, thus utilizing the polarization effects to our advantage. In Chapter 10, we discuss the detrimental aspect of birefringence in optical fibers—namely, polarization mode dispersion (PMD). The existence of birefringence in a fiber implies that the fiber supports two orthogonally polari...

An optical waveguide structure, which increases the far field radiation angle two times than that of conventional fiber, is designed and analyzed for the research of optical phased array. The structure improves the scanning scope of the optical fiber phased array effectively through designing the shape and the refractive index profile of the single mode fiber. Far field characteristic of this s...

Optical fiber is one of the most important communication media in communication system. Due to its versatile nature and negligible transmission loss it is used in high speed data transmission. Dispersion in a single mode fiber is the bottleneck of long haul optical communication systems, which limits the bit rate and repeater-less distance. Chromatic dispersion (CD) of a single mode fiber (SMF)...

This article describes Ethernet passive optical networks, an emerging local subscriber access architecture that combines low-cost point-to-multipoint fiber infrastructure with Ethernet. EPONs are designed to carry Ethernet frames at standard Ethernet rates. An EPON uses a single trunk fiber that extends from a central office to a passive optical splitter, which then fans out to multiple optical...

Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferomet...

Press-induced long-period fiber gratings exhibiting strong core-to-cladding mode coupling were formed in photonic crystal fiber. Only one resonance peak was observed over a 600 nm spectral range and the resonant wavelength was tuned over the whole range by tilting a groove plate before pressing the fiber. The resonant wavelength decreased with increasing periodicity of the grating, which was op...
