Abstract
A novel approach is presented for aligning the pulse carver and data
modulator in a dual Mach-Zehnder (MZ) modulator optical transmitter. This
technique relies solely on the photodiode detected microwave power
spectrum of the transmitted optical signal. Experimental results are
presented that illustrate the spectral property to be exploited and two
proposed techniques for designing a low cost automated carver and
modulator alignment system. A mathematical explanation for the spectral
phenomenon is presented and shown to agree quite well with measurement and
simulation results.
