Abstract

We present distributed Nyquist wavelength-division multiplexing experiments with four 25-GBd quadrature phase-shift keying modulation channels having 4% guard-band. Optical fiber-frequency conversion ensures accurate remote optical frequency alignment of the channels.

Exploring High-Precision Transmission of Optical Reference Frequencies via Wavelength Division Multiplexing

Kota Nishiyama, Mayuri Nakagawa, Kohjun Koshiji +6 more

Transmitting an ultra-high precision frequency of an optical clock via wavelength division multiplexing (WDM) is a key technology for economically realizing innovative applications enabled by significantly accurate and stable time and frequency. In this study, we investigated an optical frequency transmission method using a commercial WDM system, employing our highly stable optical frequency repeater systems with a fiber noise compensation (FNC) function. For the 20-km WDM transmission, we achieved the frequency instability of 4 × 10–15at an averaging time of 1 second (s) and reaches ~ 1 × 10–18at 34,000 s. This frequency stability enables optical clock reference frequencies to be transmitted over long distances, demonstrating the potential of our WDM link to enable the widespread deployment of the optical clock frequency at the frontier of precision.

Spatially distributed aggregation of a polarization-division multiplexed superchannel by frequency conversion in fiber

Thomas Richter, Robert Elschner, Carsten Schmidt‐Langhorst +4 more

We extend our concept for distributed ultra-dense frequency-division multiplex of single-polarization subcarriers to multiplex of polarization-division multiplexed (PDM) subcarriers. Precise frequency allocation of PDM subcarriers within a 400-Gb/s superchannel is experimentally validated with Nyquist-shaped PDM-QPSK subcarriers.

Integrated Optical Device for Frequency Conversion Across the Full Telecom C -Band Spectrum

Paul Fisher, Matteo Villa, Francesco Lenzini +1 more

High-density communication through optical fiber is made possible by wavelength-division multiplexing (WDM), which is the simultaneous transmission of many discrete signals at different optical frequencies. Vast quantities of data may be transmitted without interference using this scheme but flexible routing of these signals requires an electronic middle step, which carries a cost in latency. We present a technique for frequency conversion across the entire WDM spectrum with a single device, which removes this latency cost. Using an optical waveguide in lithium niobate and two infrared pump beams, we show how to maximize the conversion efficiency between arbitrary frequencies by analyzing the role of dispersion in cascaded nonlinear processes. The technique is presented generally and may be applied to any suitable nonlinear material or platform and to classical or quantum optical signals.

Multi-function time-frequency transmission system over optical fiber

Haijie Yu, Yitang Dai, Feifei Yin +6 more

We propose a fiber-based, multi-function time-frequency delivery system assisted by active fiber delay compensation and the wavelength division multiplexing (WDM) technology. Experimentally, three signals with different functions are transferred from the center to the remote end, while a simulated receiving signal is transferred back. All channels are delay stabilized simultaneously.

We employ a frequency comb to demonstrate a multiband wavelength-division-multiplexing (WDM)-based phase stabilization over a metropolitan-scale fiber link while maintaining a dark quantum channel. We achieve phase stability over 100 seconds, a four orders of magnitude improvement of the current state of the art.
