Recent Advances in Ultra-High-Speed Optical Signal Processing

Time Lens-Based Optical Fourier Transformation for All-Optical Signal Processing of Spectrally-Efficient Data

“…However, due to the bandwidth limitation of electronics, scaling the bandwidth of the DSP based system will also scale the number of components and their combined power consumption. On the other hand, optical signal processing (OSP) that can avoid optical to electrical to optical (OEO) conversion, has the potential to realize energy-efficient systems [9]. In addition, OSP explores nonlinear optical phenomena which have a response time on the order of femtoseconds, thus allowing for a processing bandwidth beyond one THz.…”

Advanced Optical Signal Processing using Time Lens based Optical Fourier Transformation

“…However, due to the bandwidth limitation of electronics, the number of required components and their combined power consumption scales unfavorably with the capacity. As an alternative, optical signal processing (OSP) that can offer very high bandwidth, and can avoid optical to electrical to optical (OEO) conversion, has the potential to realize energyefficient systems with very high capacity [3]. In general, OSP is considered suitable only for relatively simple functionalities.…”

InP/AlGaInAs Microring Laser and Its Application in All-optical XOR Gate

“…With the rapid development of optical fiber transmission technology, ultra high-speed signal processing capacity at the switching nodes in optical communication systems is required [1] . Unfortunately, due to the speed limitation of electronic devices, the conventional electro-optical conversion and ultra-fast electronics scheme has been accepted more and more challenges.…”
