Abstract:
1. An optical transmitter for an optical fiber transmission system, the optical transmitter comprising: a) an optical source that generates an optical signal having a wavelength at an output; b) an electro-absorption modulator having an optical input that is coupled to the output of the optical source, an electrical input that receives an electrical modulation signal, and an output, the electro-absorption modulator modulating the optical signal with the electrical modulation signal to generate a modulated optical signal at the output, wherein an absorption spectrum of the electro-absorption modulator is chosen to suppress phase and sideband information in the modulated optical signal; and c) an optical fiber that is coupled to the output of the electro-absorption modulator, wherein the suppression of the phase and the sideband information in the modulated optical signal increases an effective modal bandwidth of the optical fiber.
