Link Design and Legacy Amplifier Limitation in Flex-Grid Optical Networks
IEEE Photonics Journal, 2016 Flex-grid technology is an effective means to improve the spectral efficiency of optical communication. For a given amplifier spectral bandwidth, it gives rise to the increase in the number of optical channels as it reduces channel spacing. Therefore, in

Optical interconnect solution with plasmonic modulator and Ge photodetector array [PDF]
, 2017 We report on an optical chip-to-chip interconnect solution, thereby demonstrating plasmonics as a solution for ultra-dense, high-speed short-reach communications. The interconnect comprises a densely integrated plasmonic Mach-Zehnder modulator array that

Field patterns in periodically modulated optical parametric amplifiers and oscillators
, 2007 Spatially localized and periodic field patterns in periodically modulated optical parametric amplifiers and oscillators are studied. In the degenerate case (equal signal and idler beams) we elaborate the systematic method of construction of the ...

ANALYSIS OF THE CROSSTALK IN OPTICAL AMPLIFIERS [PDF]
ICTACT Journal on Communication Technology, 2013 In this work, we tried to analyze the crosstalk in optical amplifiers. For mathematical analysis, we have considered the Gain (G) for different amplifiers as 35 dB, 18 dB and 26 dB, respectively.

Measurement of the stimulated carrier lifetime in semiconductor optical amplifiers by four-wave mixing of polarized ASE noise [PDF]
, 1997 We present a simple experiment aimed at measuring the stimulated carrier lifetime in semiconductor optical amplifiers (SOA's). The technique relies on polarization-resolved nearly degenerate four-wave mixing (FWM) of a laser source with an amplified ...
