Nature Photonics亮点暗孤子!
暗孤子工作终于得到孤子界重视了

最近的一期nature photonics上面,亮点我们的暗孤子工作。
这份工作可是波折万分,被Optics Letters拖了近半年,拒了两次,当时感觉只能上optics communications了。幸运的是,PRA很友好的接受了我们的工作。然后又被Nature photonics亮点了,呵呵,算上石墨烯锁模被NPG亮点,这是我们第二次上NPG。

希望接下来的工作更容易展开,研究石墨烯锁模以及暗孤子的同行越来越多!也希望有更多的工作被NPG亮点,如果能发表一两篇当然是更好了。勉励一下自己吧!在2010年,走出被Optics Letters鄙视的阴影吧(略为统计了下,被Optics Letters拒了7次,只中了一次)!

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.
