Performance improvements of photonic lantern based coherent receivers
(IEEE, 2014)
In this work, the signal-to-noise ratio improvement of photonic lantern-based coherent receivers over single-mode coherent receivers is demonstrated. The signal-to-noise ratio is improved by a factor of 2.8 when other ...

(KOREAN ASSOC CRYSTAL GROWTH, INCSUNGDONG POST OFFICE, P O BOX 27, SEOUL 133-600, SOUTH KOREA, 2014)
Phosphorescent materials are known as long lasting materials including lanthanide atom doped nano particles which recently have found wide application field. Phosphorescent, classically, is the materials which have light ...
Existence of Countably Many Positive Solutions for Nonlinear Boundary Value Problems on Time Scales
(NATURAL SCIENCES PUBLISHING CORP-NSPPO BOX 32038, ISA TOWN 00000, BAHRAIN, 2014)
In this paper, we consider the existence of countably many positive solutions for nonlinear singular boundary value problem on time scales. By using the fixed-point index theory and a new fixed-point theorem in cones, the ...
