Abstract:
An electro-optic modulator for generating an output optical signal having an adjustable chirp from at least one input optical signal, the electro-optic modulator comprising:optical signal splitting means for splitting according to an adjustable coupling ratio the at least one input optical signal into a first optical signal and a second optical signal; a first modulating means for amplitude modulating the first optical signal with a positive chirp, generating a positively chirped optical signal; a second modulating means for amplitude modulating the second optical signal with a negative chirp, generating a negatively chirped optical signal; and optical signal combining means for combining according to the adjustable coupling ratio the positively chirped optical signal and the negatively chirped optical signal, generating an output optical signal; whereby the adjustable coupling ratio determines a magnitude and a sign of the adjustable chirp of the output optical signal.
