| Abstract(in English) | This paper describes reduction of photon-number uncertainty based on gain saturation of semiconductor optical amplifiers. The experimental demonstration using an optical loop with a bandpass filter having a 50-GHz 3-dB width has shown that the uncertainty is reduced in the laser field by cooperative oscillation modes continuously distributed over a frequency span of about ±1 GHz. The minimum uncertainty measured with a single photodiode was approximately equal to that of conventional coherent light. Controlling the central wavelength of the bandpass filter offered completely continuous wavelength tunability for multiple-mode lasers. The data transmission experiment at 2.5 Gbps exhibiting a floor-free bit error rate versus received power has confirmed that the tunable light source can be used for long-span transmission systems. |
