Abstract:
Optical system configured to generate and transmit a stabilized optical transmission signal, comprising:an optical transmission line;a first signal source connected to said optical transmission line and including a first laser having a number of separate laser modes having laser wavelengths within a first wavelength band containing the gain curve of the first laser, said first signal source being configured to generate and transmit an optical transmission signal over said optical transmission line;an optical connection;a second signal source configured to generate an optical injection signal, said second signal source being coupled to the first signal source via the optical connection coupled to the first laser,wherein the second signal source contains an optical noise source configured to generate a narrow-band noise signal having wavelengths within a second wavelength band so as to be included with the optical injection signal in a manner such that the second wavelength band of the noise signal lies within the first wavelength band of the first laser, and that the first laser has at least one laser mode having a laser wavelength within the second wavelength band, and further wherein the first laser operates or is forced to operate in said at least one laser mode having a wavelength within the second wavelength band.
