Gajda, Andrzej (2017)
Traffic in data communication networks has seen continuous growth over many decades. Taking the example of transport networks we observe a growth rate of about 60% per year in capacity. The increase in traffic is supported by various technologies but mainly driven by applications related to social media, moving images, internet of things etc. An important contender for future increase of fiber ...Waveguide integrated MQW p-i-n photodiodes
Zhou, Gan (2017)
In this work, waveguide integrated multiple quantum well p-i-n photodiodes are developed and characterized. Compared to bulk photodiodes, multiple quantum well photodiodes have special properties including a large and tunable polarization dependent loss. It makes multiple quantum well photodiodes a potential candidate for various applications, especially in polarization-diversity coherent optic...Fiber optical parametric amplifiers in optical communication systems
Marhic, Michel E. ; Andrekson, Peter A. ; Petropoulos, Periklis ; Radic, Stojan ; Peucheret, Christophe ; Jazayerifar, Mahmoud (2015)
The prospects for using fiber optical parametric amplifiers (OPAs) in optical communication systems are reviewed. Phase-insensitive amplifiers (PIAs) and phase-sensitive amplifiers (PSAs) are considered. Low-penalty amplification at/or near 1 Tb/s has been achieved, for both wavelength- and time-division multiplexed formats. High-quality mid-span spectral inversion has been demonstrated at 0.64...
