Characterizing Jitter Histograms for Clock and DataCom Applications

This TecForum will discuss the drawbacks of quantifying histograms with peak-to-peak measurements and recommend more thorough characterization methods that reflect true device performance thereby enabling engineers to accurately make pass-fail decisions. Included is a discussion of the common measurements that are used to analyze clock signals such as phase noise, period jitter and cycle-to-cyc...

Integrated Photonic Devices and Applications for 100GbE-and-Beyond Datacom

We review recent progress in integrated photonics devices and their applications for datacom. In addition to current technology used in 100-Gigabit Ethernet (100GbE) with a compact form-factor of the transceiver, the next generation of technology for 400GbE seeks a larger number of wavelengths with a more sophisticated modulation format and higher bit rate per wavelength. For wavelength scalabi...

Progress on Ultra-Dense Quantum Communication Using Integrated Photonic Architecture

The goal of this program is to increase the private information capacity of optical channels. Here we report on the theoretical and experimental progress, including the development of a large-alphabet quantum key distribution protocol that uses measurements in mutually unbiased bases. The goal of this program is to increase the private information capacity of optical channels. Here we report on...

Ultra stable all-fiber telecom-band entangled photon-pair source for turnkey quantum communication applications.

We demonstrate a novel alignment-free all-fiber source for generating telecom-band polarization-entangled photon pairs. Polarization entanglement is created by injecting two relatively delayed, orthogonally polarized pump pulses into a piece of dispersion-shifted fiber, where each one independently engages in four-photon scattering, and then removing any distinguishability between the correlate...
