| 英文摘要 | An optical transmission system includes a Fabry-Perot semiconductor diode laser, a transmitter and a receiver. The laser operates in a continuous-wave regime on an inhomogeneously broadened optical transition of the active region of the laser. A spectral bandwidth of an output lasing spectrum of the laser is greater than 5nm and a spectral power density of the laser is greater than 2mW/nm such that an optical power of the laser is greater than 1OmW. The laser provides a plurality of longitudinal modes (optical signals) of the resonator at different wavelengths. A relative intensity noise of at least ten longitudinal modes does not exceed -120 dB /Hz at 0.1GHz, -130 dB /Hz at 0GHz and - 140 dB /Hz at 10GHz. The transmitter is capable of providing modulation to each lasing wavelength independently and the receiver is capable of providing detection to each lasing wavelength independently. |
