Hello Lalit
LED has a broad spectral region over wavelengths.if you want to use specific wavelength then use FBG(fiber bragg grating) which will reflect the wavelength according to the spacing among the gratings and transmit the rest part.For better information please attach a paper you are working on or clear your objectives.I have given a some links for better understanding of SAC ocdma
