Effects of nonuniform photon distribution on high speed response in semiconductor distributed feedback lasers

Applied Physics Letters (1995)

Jing Feng T. R. Chen A. Yariv

The high speed performance of distributed feedback (DFB) lasers, with nonuniform longitudinal photon density distributions, has been analyzed. It was found that the relaxation resonance frequency and damping rate of the lasers depended on the distribution of traveling electric fields in the lasers. A two section DFB laser was used to demonstrate the effects of spatial hole burning on the high speed response of the DFB laser. By adjusting the photon density distribution in the laser through nonuniform current injection, the resonance frequency and damping rate of the two section DFB laser can be changed even if the output optical power is kept constant.

<title>Preliminary design of the main amplification stage of Technical Integration Line (TIL) for the SG-III laser facility</title>

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (1998)

Jing Feng Xiao Min Zhang Qihua Zhu Yongzai Man Hansheng Peng

Technical Integration Line (TIL) is the full scale two-beam prototype for Shenguang-III laser facility. A four pass amplifier system with small aperture beam reverser has been designed as the main amplification stage for TIL, which will produce 1 kJ of UV radiation on the target from each beam in 1-3 nanoseconds shaped pulses. Two schemes were considered in the preliminary design, one of them employed only small aperture Pockels cell in the reverser, and the other used another larger plasma electrode Pockels cell in the main beam line. Simulated by a fast-running lumped-element computer code, the configuration of baseline scheme for TIL was settled. The basic requirements for optical elements were raised during simulation processing.

Dietary Oregano Oil Supplementation Improved Egg Quality by Altering Cecal Microbiota Function in Laying Hens

Animals (2024)

Lihong Xian Yan Wang Peng Da Lei Zang Yongli Xu

Improving egg quality is one of the main objectives of the poultry industry. The objective of this study was to investigate the effects of dietary oregano oil supplementation with different concentrations on the egg quality, intestinal morphology and cecal microbiome of late-phase laying hens. A total of 300 55-week-old Snowy white laying hens were randomly divided into five groups and fed a basal diet (control) or basal diets supplemented with oregano oil at 25, 50, 75 and 100 mg/kg (O25, O50, O75 and O100) over a 100-day period. Compared with the control group, eggshell thickness and eggshell weight were increased significantly in eggs when oregano oil was added (p < 0.05). The highest content of polyunsaturated fatty acids (PUFAs) and C18:2n6c was observed in yolks with 25 mg/kg supplement among 5 groups (p < 0.05). The highest average content of riboflavin in egg yolk and thiamine in egg white was observed in the O25 group (p < 0.05). When the supplemental levels of oregano oil were 25 mg/kg and 50 mg/kg, the selenium and phosphorus content in the egg was significantly increased (p < 0.05). The ratio of villus height to crypt depth (V/C) and villus height of the small intestine was significantly increased compared with the chickens fed the basal diet (p < 0.05). Compared with the control group, the abundance of Megamonas was increased in the O50 group (p < 0.05). The unclassified_o__Bacteroidales in the O25 group were significantly higher than those in the other four groups (p < 0.05). These differential microorganisms were significantly correlated with egg quality characteristics. Dietary supplementation of oregano oil can significantly improve egg quality via gut microbiota alteration in laying hens.

Increase of SNR of ultra-short pulse laser at 800nm with saturated absorption

Laser Technology (2009)

Jing Feng

High signal-to-noise ratio (SNR) is very important in the interaction between high energy ultra-short laser and materials. In order to increase the SNR of ultra-short laser,the saturation absorption property of Nd:glass laser at the neighborhood of 800nm was studied. The relationship between the nonlinear transmissivity and normalized energy density of the combined Nd:glass system was obtained after solving the rate equations. For an optional 800nm laser pulse,making use of the frequency differences between amplified spontaneous emission pulse,modulation pulse and the main laser pulse,combining different types of Nd:glass material of optimizing the comprehensive data of the density,thickness...etc,the absorption spectrum of the combined Nd:glass system was designed reasonably. Computation results indicate that the noise is compressed effectively,and the SNR is increased a lot.

A spectroscopic refractometer based on plasmonic interferometry

Journal of Applied Physics (2016)

Jing Feng Domenico Pacifici

We describe the design, fabrication, and testing of a spectroscopic refractometer that employs plasmonic interferometry to measure the optical dielectric functions of materials in the visible range. The proposed device, dubbed a plasmonic refractometer, consists of an array of slit-groove plasmonic interferometers etched in a ∼300 nm-thick metal film (silver or gold) with arm lengths varying in steps of 25 nm up to ∼8 μm. The nano-groove in each interferometer is able to generate propagating surface plasmon polaritons efficiently in a broad wavelength range, without requiring prism- or grating-coupling configurations. An integrated microfluidic channel ensures uniform delivery of dielectric materials in liquid phase. Spectrally resolved plasmonic interferograms are generated by measuring light transmission spectra through the slit of each slit-groove plasmonic interferometer and plotting the normalized intensity as a function of arm length (0.26–8.16 μm) and incident wavelength (400–800 nm) for various combinations of metal/dielectric materials. Fits of the plasmonic interferograms with a surface plasmon interference model allow determination of the refractive index dispersion of a broad class of dielectric materials, over a wide range of wavelengths and dielectric constants. As proof of concept, we extract and report the dielectric functions of representative materials, such as silver, gold, water, methanol, and ethanol.
