Abstract

A novel modulation technique is presented which facilitates the transmission of high frequency, fractional bandwidth signals in fibers. This approach uses the advantages of modelocked semiconductor lasers and external modulators. Narrow band (~ 10 GHz) modulation can be readily achieved at high center frequencies. Experimental realization of this concept is demonstrated with an acoustooptic modulation of modelocked optical pulses from a GaAs laser diode at a center frequency of 2.05 GHz and a bandwidth of 68.7 MHz.
