Nature Photonics亮點暗孤子

Nature Photonics亮點暗孤子！

暗孤子工作終於得到孤子界重視了

最近的一期nature photonics上麵，亮點我們的暗孤子工作。
這份工作可是波折萬分，被Optics Letters拖了近半年，拒了兩次，當時感覺隻能上optics communications了。幸運的是，PRA很友好的接受了我們的工作。然後又被Nature photonics亮點了，嗬嗬，算上石墨烯鎖模被NPG亮點，這是我們第二次上NPG。

希望接下來的工作更容易展開，研究石墨烯鎖模以及暗孤子的同行越來越多！也希望有更多的工作被NPG亮點，如果能發表一兩篇當然是更好了。勉勵一下自己吧！在2010年，走出被Optics Letters鄙視的陰影吧（略為統計了下，被Optics Letters拒了7次，隻中了一次）！

Solitons

Dark laser debut

Phys. Rev. A 80, 045803 (2009)

Although lasers are well known to emit bright pulses of light, a team of researchers in Singapore have now demonstrated the exact opposite — a fibre laser that emits a stream of 'dark pulses'. The erbium-doped fibre laser developed by Han Zhang and co-workers from Nanyang Technological University emits a series of intensity dips in a continuous-wave background of laser emission. The scientists attribute the phenomenon to dark-soliton shaping in the laser cavity. The laser consists of a fibre ring cavity that contains a 5 m length of erbium-doped fibre to provide optical gain and a 150 m length of dispersion compensation fibre. It also features a polarization controller, an isolator, a 50:50 output coupler and a multiplexer for injecting 1,480 nm pump light into the cavity. The researchers observed a series of dark pulses at the fundamental cavity repetition rate. They also say that by carefully controlling the pump strength and orientation of the polarization controller, the output could be reduced to a single dark pulse. Analysis suggests that the dark pulses have a hyperbolic-tangent profile and a typical pulse width of 8 ps, and are transform-limited.
