      Hi all,
      How to generate a dual-tone signal, here tone refers to the frequency of the carrier that is to be used for modulating the CW laser output. is multiplexing necessary for this.?

      Regards

      Hi Dhiman,

      One way I have seen other than multiplexing is the use of a broadband light source along with narrowband filters that each only pass the spectrum of a specific frequency (which is the carrier frequency). And the number of filters used is dependent on the tones you want the light source to have.

      Regards

        Hi Alistu, I think that will be quite complex and expensive to do so, do you have any sample design or paper to implement as you have mentioned here that uses this technique. Thank you for the reply.

        Regards
