Abstract
In an embodiment, an optical communication system includes an optical transmitter and an optical discriminator. The optical transmitter is configured to emit a frequency modulated signal having a bit rate frequency and a frequency excursion between 20% and 80% of the bit rate frequency. The optical discriminator is configured to convert the frequency modulated signal to a substantially amplitude modulated signal and includes a delay line interferometer (DLI). The DLI includes an input, an output, a first optical path coupling optical signals from the input to the output and a second optical path coupling optical signals from the input to the output. The first and second optical paths have different lengths.
