Soliton blue-shift in tapered photonic crystal fiber

, 2010
We show that solitons undergo a strong blue shift in fibers with a dispersion landscape that varies along the direction of propagation. The experiments are based on a small-core photonic crystal fiber, tapered to have a core diameter that varies ...

The Bimodal Galaxy Stellar Mass Function in the COSMOS Survey to z~1: A Steep Faint End and a New Galaxy Dichotomy [PDF]

, 2009
We present a new analysis of stellar mass functions (MF) in the COSMOS field to fainter limits than has been previously probed to z~1. Neither the total nor the passive or star-forming MF can be well fit with a single Schechter function once one probes ...

Improving Peak-Wavelength Method to Measure Junction Temperature by Dual-Wavelength LEDs

IEEE Access, 2017
In this paper, the improvement of the method measuring the junction temperature of lightemitting diodes (LEDs) has been studied experimentally. A practical method is proposed with only three measurement procedures.

Sand-Dust Image Restoration Based on Reversing the Blue Channel Prior

IEEE Photonics Journal, 2020
Images acquired under sand-dust weather conditions are severely degraded, with low contrast and severe color shift. The reason is that, due to the influence of sand-dust particles, light is scattered and absorbed, resulting in a blurred image and low ...

A Large Blue Shift of the Biexciton State in Tellurium Doped CdSe Colloidal Quantum Dots

, 2008
The exciton-exciton interaction energy of Tellurium doped CdSe colloidal quantum dots is experimentally investigated. The dots exhibit a strong Coulomb repulsion between the two excitons, which results in a huge measured biexciton blue shift of up to 300

Stereotactic Body Radiation Therapy for Pediatric, Adolescent, and Young Adult Patients With Osteosarcoma: Local Control Outcomes With Dosimetric Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.

Blue shift of CdSe/ZnS nanocrystal-labels upon DNA-hybridization

Journal of Nanobiotechnology, 2008
Luminescence color multiplexing is one of the most intriguing benefits, which might occur by using semiconductor Quantum Dots (QDs) as labels for biomolecules.

Near field spectral dispersion of dipole radiation: The maximum red and blue shifts, and the near and far field boundary

Results in Optics, 2021
Spectral dispersion of dipole radiation in near field zone is studied. Spectral changes are demonstrated using polychromatic incident light of Gaussian spectral profile as test examples. Both red and blue shifts are possible.

Blue-shifting, asymmetric quantum wells

Electronics Letters, 1996
Asymmetric, (100) blue-shifting quantum wells have been fabricated using δ-doped layers at each well-barrier interface. The photoluminescence peaks depend on the δ-dopant concentration as predicted, and blue shifts of 38 nm have been measured for a factor 20 increase in optical pump power.
