The distribution of high spectral purity reference signals over optical fibre in future telecommunication satellite payloads is presented.
We experimentally demonstrate the transformation of 42.7-Gb/s optical DPSK signals into high-quality duobinary signals by optical filtering in an athermal delay-interferometer filter.
We propose and demonstrate a simple method to improve both the receiver sensitivity and spectral efficiency of the optical duobinary transmission system.
We propose and demonstrate a simple method to improve both the receiver sensitivity and spectral efficiency of the optical duobinary transmission system.
We describe the use of emission lineshapes for determining the mechanisms of excited state formation and assessing the validity of an actinometer.
In a high-speed, long-haul, fiber-optic communication system, fiber dispersion can cause serious performance degradations.
We demonstrate the use of an optical equalizer to allow a 42. 7-Gbaud (85.4-Gb/s) NRZ-DQPSK signal to tolerate the narrow optical filtering required in high-spectral-efficiency systems.
We demonstrate the use of an optical equalizer to allow 42.7-Gbaud (85.4-Gb/s) return-to-zero differential quadrature phase-shift keyed signals to better tolerate the narrow optical filtering requi
We present the first optical equalizer monolithically integrated with a semiconductor optical amplifier.
Centralized data centers (DC) cannot fulfill the latency targets of the 5G mobile network due to the large fiber propagation delays. Processing resources need to move closer to the end devices.
