“…Angular misalignment, and to a greater extent longitudinal separation, contribute less loss than axial displacement [12]. Rotational stage alignment was not feasible in this setup, since fiber alignment stages with rotation capability are generally very large, so emphasis was put towards minimizing axial and longitudinal displacement between optical fiber and SOA waveguide end.…”

A photonic switch using two series-connected, reverse-biased semiconductor optical amplifiers integrated onto a single device has been proposed and switching operation has been verified experimentally. The switching operates on two principles; an electrical bistability arising from the connection of two p-in structures in series, and the quantum confined Stark effect in reverse-biased multiple quantum well structures. The result is an electroabsorption modulation of the light through the SOAs due to the alternating voltage states. The system simultaneously produces outputs with both inverted and non-inverted hysteresis behavior, with experimental switching speeds demonstrated up to 400 kHz for a reverse-bias voltage of =2.000V. DEDICATION I dedicate this thesis to Stephanie. Thank you for your loving support and for helping me through the tough times. ACKNOWLEDGEMENTS I would like to acknowledge all of the Rose-Hulman faculty and staff, and my fellow PHOE students, who have all helped me in my time at this great school. Without their knowledge, guidance, and assistance I could not have achieved the things that I have today. Specifically, I would like to thank: Dr. Azad Siahmakoun, thank you for affording me a chance to return to Rose-Hulman and pursue a graduate education and research in optics, and for always believing in me. Dr. Robert Bunch, thank you for the years of keen advice and guidance, both academic and professional. Dr. Sergio Granieri, thank you for always being there to help and for encouraging me to pursue graduate education in optics in the first place. I guess you were right all along. Dr. Charles Joenathan, thank you for all of your assistance through the years, and for helping me return to Rose-Hulman to continue my education in optics. Dr. Paul Leisher, thank you for your help and advice through the years. You also strongly encouraged me to pursue a graduate education in the first place. I should have listened. Pam Hamilton, thank for all of your helpful advice through the years, and for always making sure that I was on top of things. Ben Webster, thank you for all of your help and for making my GA work hours much more enjoyable. Roger Sladek, thank you for all of your help and insight on the projects and designs that I have worked on through the years. Your work has helped make my life easier countless times.

This paper reviews the theoretical analysis of light propagation we have carried out on multimode multi-step index (MSI) optical fibres. Starting from the Eikonal equation, we derive the analytical expressions that allow calculating the ray trajectories inside these fibres. We also analyse the effects of leaky rays on the transmission properties of MSI fibres. For this purpose, a single analytical expression for the evaluation of the ray power transmission coefficient is calculated. Afterwards, we investigate the effects of extrinsic and intrinsic coupling losses on the performance of MSI fibres, providing analytical expressions to calculate the coupling loss and, also, determining the most critical parameters. Finally, we carry out a comprehensive numerical analysis of the fibre bandwidth under different source configurations.Cross-section photographs of two different MSI-POFs (left: Eska-Miu fibre; right: TVER fibre).

“…The position accuracy of the fiber must be better than ±2.5 μπι to achieve an insertion loss objective for the optical connection of less than 0.5 dB. 8 The first prototypes of the connector were made of stainless steel by machining the plates in pairs. The insertion loss measured on connec tions made of matched plates was 0.4 dB.…”
