According to the requirements of the fiber optic gyro with high-accuracy, the high-power and high-accuracy double-pass backward (DPB) erbium-doped fiber source was used. The optimization parameters of high-power, high-efficiency erbium-doped superfluorescent fiber source are designed. Near Gaussian-shaped spectrum of erbium-doped superfluorescent fiber source was designed. Near Gaussian-shaped spectrum...
We present a numerical study of the interactions between two solitons that split from two picosecond pulses with different time intervals during supercontinuum generation in a photonic crystal fiber. We demonstrate the manner in which the soliton interaction evolves along the fiber and affects the dynamics of the soliton pair. The results show that spectral broadening can be attributed to interpulse...
This paper proposes a novel frequency-shifted interferometry (FSI) fiber cavity ring-down (CRD) gas sensing with dual-wavelength differential optical absorption that requires no modulation to a continuous-wave source or without fast detection and switching electronics. The fiber cavity is constructed from standard fiber optical components that include a micro-optical gas cell. FSI-CRD experiments...
Reshaping of ultrashort (400fs-FWHM) Gaussian-like pulses into 2ps-flat-top pulses is experimentally demonstrated using a specially apodized linearly-chirped fiber Bragg grating (LC-FBG) working in transmission.
In recent years, Smart grid has drawn much more attention because of improving environmental consciousness and $3.4 billion funding from the Obama Administration in the United States. A reliable communication network is the core of smart grid. This paper addresses the communication demand of constructing smart grid. Various communication technologies are discussed, including wired and wireless technologies...
We demonstrate a graphene based saturable absorber mode-locked Nd:YVO4 solid-state laser, generating ∼14nJ pulses with ∼1W average output power. This shows the potential for high-power pulse generation.
This paper presents a wireless distributed system to measure transient electromagnetic field in power substations. Taking advantage of flexible short-range wireless technique, the system allows flexible multi-node simultaneous measurement while is of compact size and low cost.
We investigate two different node structures with fiber delay lines (FDLs) in optical burst switching networks: FDL share per node and FDL share per link. We study the roles of maximum delay and the single FDL element granularity in FDL share per node. Our simulations show that FDLs with limited delay can effectively improve the network performance in terms of burst loss probability, but increasing...
