Abstract
An optical transmitter includes a light source and an SBS suppression circuit coupled to the light source. The light source is operable to generate an optical signal having one or more wavelengths. The optical signal has a signal spectrum having an upper band limit and a lower band limit. The SBS suppression circuit is operable to communicate a noise current for receipt by the light source. The noise current is operable to broaden the signal spectrum of the optical signal. The light source operates to convert the noise current into a noise component of the signal spectrum that resides between the upper band limit and the lower band limit.

An optical transmitter comprising:
- a light source operable to generate an optical signal having one or more wavelengths, the optical signal comprising a signal spectrum having an upper band limit and a lower band limit;
- and
- a stimulated Brillouin scattering (SBS) suppression circuit coupled to the light source and operable to communicate a noise current for receipt by the light source, the noise current operable to broaden the signal spectrum of the optical signal, wherein the light source operates to convert the noise current into a noise component of the signal spectrum that resides between the upper band limit and the lower band limit.
A method of broadening a line-width of an optical signal, the method comprising:
- generating a noise current operable to broaden a signal spectrum of an optical signal;
- combining the noise current and a drive current;
- and
- generating an optical signal using the combination of the noise current and the drive current, the noise current operable to produce a noise component in the optical signal.
The method of claim 11, wherein the noise component operates to broaden the signal spectrum by at least 300 MHz.
A method of broadening a line-width of an optical signal, the method comprising:
