white LED spectrum
hi, right now I’m constructing M-ary PAM system for visible light communication system using LED (IMDD) so I just notice the wavelength or optical spectrum produce by LED is pointy/peak at defined wavelength. I need to simulate using real life white led spectrum from 400nm – 750nm so I need some suggestion to get the spectrum. should I just use few CW laser and define the power and wavelength imitating LED spectrum or should I use wavelength multiplexor and combine number of LED together or maybe anyone have any other suggestion?
