Wavelength Conversion |
8.1 INTRODUCTION
The possibility of generating signals at a desired frequency by all-optical wavelength conversion is extremely attractive for many different applications, including telecommunications, sensing, medicine, and defense. In particular, wavelength-conversion technologies are essential in future optical communication networks for improving the effective use of fiber transmission bandwidths and to solve the problem of network congestion caused by wavelength contention [1,2,3]. The capability of wavelength converting cheap and reliable optical sources into very different frequency bands as compared to the original is also very important [4,5].
Wavelength conversion has been performed using optical/electrical/optical ...
