Laser Diode Frequency Control for Multiwavelength (WDM) Optical Communications
The simultaneous use of many wavelengths will increase the throughput of point to point optical communication systems and lead to the development of networks where the routing is achieved using the wavelength values as the keys for identification.1 For relatively dense systems, the laser wavelengths will have to be controlled precisely to avoid crosstalks or wrong identification. In this work, two distinct approaches are considered to set and to maintain the wavelength of an ensemble of laser sources in the 1.5 um region.
