Abstract
A method and apparatus are provided for modulating a coherent light source with a digital) signal. The method includes the steps of splitting the digital signal into a first and a second copy and mixing the first copy with a clock signal to provide a first modulation component. The method further includes the steps of inverting the second copy and delaying the clock signal by one-hundred eighty degrees. The method also includes the steps of mixing the inverted second copy with the delayed clock signal to provide a second modulation component and summing the first and second modulation components.
