SBS suppression in fiber amplifiers with a broadband seed

Jeffrey Owen White, David M. Brown, A. J. Goers, Brice M. Cannon et autres

We present a scalar, time-dependent, plane-wave model for stimulated Brillouin scattering (SBS) within a fiber amplifier having a seed linewidth comparable to, or greater than, the Brillouin frequency shift. The broadband model introduces the existence of a backward anti-Stokes wave, in addition …

Evaluation of the robustness of polarization attraction for 107-GBaud NRZ-BPSK after long-haul 100-GHz DWDM transmission

A. Delong, W.S. Astar, Brice M. Cannon, G. M. Carter

, relative to matched-filter reception theory. After long-haul 100-GHz DWDM transmission in a recirculating loop, PA on the output signal was found to achieve approximately the same receiver sensitivity performance, as that of the back-to-back case. From these experiments, it is concluded …

Precision Microwave Frequency Transfer over Dual Free-Space Optical Links

Eric J. Adles, N.G. Bos, Brice M. Cannon, Michael L. Dennis et autres

We have developed a complete system for the transfer of an X-band microwave reference frequency over two independent free-space optical links. The links use optical frequency combs, linear optical sampling, and two-way time transfer techniques to derive femtosecond precision correction signals for …

Lasercomm system development for high-bandwidth terrestrial communications

Juan C. Juarez, Katherine T. Souza, Natalie Bos, Andrea M. Brown et autres

In recent years, various terrestrial free-space optical (FSO) communications systems have been demonstrated to achieve high-bandwidth communications between mobile platforms. The terminal architectures fall into three general categories: (1) single aperture systems with tip/tilt control, (2) multi-aperture system with tip/tilt control, and …

Simultaneous Polarization-Insensitive Phase-Space Trans-Multiplexing and Wavelength Multicasting via Cross-Phase Modulation in a Photonic Crystal Fiber at 10 GBd

Brice M. Cannon

This thesis investigates the all-optical combination of amplitude and phase modulated signals into one unified multi-level phase modulated signal, utilizing the Kerr nonlinearity of cross-phase modulation (XPM). Predominantly, the first experimental demonstration of simultaneous polarization-insensitive phase-transmultiplexing and multicasting (PI-PTMM) will be discussed. …

Polarization-Insensitive Wavelength Conversion and Transmultiplexing in AlGaAs Waveguides

Gary M. Carter, Brice M. Cannon, Tanvir Mahmood, W.S. Astar

By exploiting the inherent birefringence and strong third-order susceptibility of AlGaAs waveguides, we demonstrated several all-optical polarization-insensitive nonlinear-optical signal processing operations. Additionally, undesirable two-photon absorption was minimized via band gap engineering.

Polarization-Insensitive Phase-transmultiplexing of CSRZ-OOK and RZ-BPSK to RZ-QPSK via XPM in a PCF

Brice M. Cannon, Tanvir Mahmood, W.S. Astar, P. Boudra et autres

By utilizing cross-phase modulation, we demonstrated polarization-insensitive phase-transmultiplexing to RZ-QPSK in a photonic crystal fiber. The measured receiver sensitivity penalty at 10−9 BER was ≈1.8 dB for a randomly polarized CSRZ-OOK signal.
