Simple all-Fiber-Optic Component for first-order polarization mode dispersion compensation
Optical Engineering, 2002Co-Authors: Young Wuk Lee, Ho Jin Jeong, Jung Hyung Pyo, Byoung Yoon Kim, Kyong Mo Yoon, Geun Young Kim, Yong Gi LeeAbstract:A simple and reliable all-Fiber-Optic Component for a first-order polarization mode dispersion compensator is presented and tested in a 10-Gbit/s transmission system. The proposed Component incorporates tunable differential group delay (DGD) provided by several pieces of polarization maintaining (PM) Fibers of different DGD that were spliced together with short lengths of single-mode Fibers between them. The total DGD of the compensator is determined by the alignment of fast and slow axes of the PM Fiber sections. Applying this Component as a first-order polarization mode dispersion (PMD) compensator, we demonstrate that a Component with seven pieces of PM Fiber segments could possibly compensate the first-order PMD up to 63.5 ps with 1-ps steps and a switching time of 300 ms. We also optimize the number of PM Fiber sections in this Component for a first-order PMD compensation in a 10Gbit/s system based on experimental results.

Optical vector network analyzer for single scan measurements of loss group delay and polarization mode dispersion
Applied Optics, 2005Co-Authors: Dawn K Gifford, Brian J Soller, Matthew S Wolfe, Mark E FroggattAbstract:We present a method for measuring the complete linear response, including amplitude, phase, and polarization, of a Fiber-Optic Component or assembly that requires only a single scan of a tunable laser source. The method employs polarization-diverse swept-wavelength interferometry to measure the matrix transfer function of a device under test. We outline the theory of operation to establish how the transfer function is obtained. We demonstrate the enhanced accuracy, precision, and dynamic range of the technique through measurements of several Components.

founding a Fiber Optic Component and sensor business
2008Co-Authors: Ingolf BaumannAbstract:When an engineer is going to start his own business, only a few people are able to give some competent advice based on their own experiences; most entrepreneurs might face this actuality. Since the primary business idea is related to the high-tech business sector, it may even become a real challenge to gather all necessary information that enables the founder to realize his ideas. However, the founder has to overcome this first barrier, being much more on his own compared to a business creation in a more traditional field. The basic reasons for this are the extremely high customization effort for most innovations, serving the market’s demands, and a lack of established distribution channels for the product. Thus, in this state it is quite difficult to prove that the company is making progress and that the business plan is a realistic scenario. As a matter of fact, no other person is as deeply involved in the young company’s technology and/or services as the founder—only this competence might be able to dispel the investors’ doubts. The following lines may give an overview about my way of creating a successful business.
