Superstructured gratings enable OCDMA/WDM compatibility

Optical-code-division multiple access (OCDMA) technology based on superstructured fiber Bragg gratings for code generation and recognition offers great promise for a variety of network applications, particularly in the metro and access sectors. Wavelength selectivity means it is inherently compatible with WDM technology and can simultaneously support different coding schemes, repetition rates, and wavelength channels.
