WebAll-optical regeneration of differential phase-shift keying signals based on phase-sensitive amplification is described. Nearly ideal phase regeneration can be achieved in the undepleted-pump regime, and simultaneous amplitude and phase regeneration can be realized in the depleted-pump regime. © 2004 Optical Society of America PDF Article WebTissue optical clearing in conjunction with advanced labeling, imaging, and data processing techniques holds great promise for the precise and accurate morphological analysis of nerve tissues and target organs , which will predictably aid the advancement of experimental neural regeneration studies and potentially the discovery of clinical ...

Such repeaters are used to extend the reach of optical communications links by overcoming loss due to attenuation of the optical fiber. Some repeaters also correct for distortion of the optical … See more Optical regenerations are classified into 3 categories by the 3 R's scheme. 1. R : reamplification of the data pulse alone is carried out. 2. 2R : in addition to reamplification, pulse reshaping is carried out. E.g.: See more Due to the high data rates that can be achieved with optical systems, OEO repeaters are expensive to implement as electronics to handle those high data rates are expensive and difficult to construct. Also, since one repeater is required for each wavelength, … See more An alternative method of regeneration is through all-optical regenerators without the additional requirement to convert back and forth between optical and electronic signals. Non-linear … See more Cost efficiency has led to OEO repeaters being largely replaced in long-haul systems by optical amplifiers since one (broadband) amplifier can be used for many wavelengths in a See more
