Two-dimensional materials based nonlinear optical devices: past and future
Han Zhang,

Originating from the emerging and intensively research of graphene, there have been tremendous improvements in the area of two dimensional materials (2D) based photonics. Its unique optoelectronics characteristics and the capability of being easily stacking to multilayer heterostructures have been proved to be able to generate some novel and distinctive optoelectronic devices, such as transparent conductive films, polarizers, saturable absorbers, optical modulators, photodetectors, and so on. Recently, we have experimentally found that beyond graphene, other two-dimensional layered materials such as topological insulators, MoS2 etc. also possess wideband nonlinear optics response using Z-scan measuring technique. By using the lager two or three order nonlinear properties, we have successfully demonstrated optical modulators, wavelength converter, polarizer and so on. And By using the saturable absorption property of these 2-D materials, different types of optical saturable absorber devices have been developed for the passive mode locking, passive Q-switching or single longitudinal mode of lasers. We can conclude that it is more flexible in manufacturing desirable and given photonics devices, and the performance of novle photonics devices can also be greatly boosted. It is expected that the research of two-dimensional nano-materials photonics will be developed predominantly in optoelectronic devices applications

Yu-Hsiang Lin Generation of double-peaked laser spectral compression in a dispersion-increasing fiber
Yu-Hsiang Lin,Chen-Bin Huang,

The generation of double-peaked laser spectral compression is demonstrated using a dispersion-increasing fiber (DIF). The experimental results are in excellent agreement as compared to numerical calculations.

Ting-Hui Chen Bunched Soliton Evolution in Fundamentally and Harmonically Passive Mode-Locked Erbium-Doped Fiber Laser
Ting-Hui Chen,Yung-Hsiang Lin,Gong-Ru Lin,

Bunched soliton formation and evolution in the polarizer- and absorber-free erbium-doped fiber laser is investigated. Even a weak polarization dependent loss can enable the passive mode-locking and vary its order from fundamental to harmonic condition, while the soliton forms are evolved into bunched state by simply enlarging the net gain.

Yen-Hsu Chou Sub-ps all-fiber all-normal-dispersion P-APM mode-locked Yb-doped fiber laser
Yen-Hsu Chou,Shang-Ying Wu,Yinchieh Lai,

An all-fiber, all-normal-dispersion, polarization –APM passive mode-locked Yb-doped fiber laser is experimentally demonstrated at the 1um wavelength. With an external grating pairs for linear pulse-width compression, the final pulse-width can be as short as 693fs.

Chen-Wei Chan Bound pulse generation from passive mode-locked Yb-doped fiber laser at net normal dispersion region
Chen-Wei Chan,Ja-Hon Lin,

The bound state of multiple soliton were experimentally demonstrated from a passive mode-locked Yb-doped fiber laser based on the nonlinear polarization mechanism at net normal dispersion region through adjustment of the waveplate. After pulse compression by the external grating pairs, the compressed bound pulses below 1 ps were successfully demonstrated.
