Polarization Optics In Telecommunications

I have written this book to ?ll a void between theory and practice, a void that Iperceivedwhileconductingmyownresearchanddevelopmentofcomponents and instruments over the last ?ve years. In the chapters that follow I have pulled materials from the technical and patent literature that are relevant to the understanding and practice of polarization optics in telecommuni- tions, material that is often known by the respective experts in industry and academia but is rarely if ever found in one place. By bringing this material intoonemonograph,andbyapplyingasingleformalismthroughout,Ihopeto create a “base level” upon which future research and development can grow. Polarization optics in telecommunications is an ever-evolving ?eld. Each yearsigni?cantadvancementsaremade,punctuatedbyimportantdiscoveries. The references upon which this book is based are only a snap-shot in time. Areasthatremainunresolvedatthetimeofpublicationmayverywellbecl- i?ed in the years to come. Moreover, the focus of the ?eld changes in time: for instance, there have been few passive nonreciprocal component advancements reported in the last few years, but PMD and PDL advancement continues with only modest abatement.

The strong investments into optical telecommunications in the late 1990s

resulted in a wealth of new research, techniques, component designs, and

understanding of polarization effects in fiber. Polarization Optics in

Telecommunications brings together recent advances in the field to create a

standard, practical reference for component designers and optical fiber

communication engineers. Beginning with a sound foundation in

electromagnetism, the author offers a dissertation of the spin-vector

formalism of polarization and the interaction of light with media.

Applications discussed include optical isolators, optical circulators,

fiber collimators, and a variety of applied waveplate and prism

combinations. Also included in an extended discussion of polarization-mode

dispersion (PMD) and polarization-dependent loss (PDL), their

representation, behavior, statistical properties, and measurement. This

book draws extensively from the technical and patent literature and is an

up-to-date reference for researchers and component designers in industry

and academia.
