OPTICAL AND STRUCTURAL STUDIES OF ANODIC COPPER PIGMENTED TITANIUM PHOTOCATALYST
(University of Eldoret, 2020)
Thousands of lives have been lost worldwide due to the shortage of clean water resources
caused by waste water disposal challenges from manufacturing and processing industries,
population growth and long-term droughts. ...
Performance of 1550 nm VCSEL at 10 Gb/s in G.655 and G.652 SSMF
(International Journal of Sustainability Management and Information Technologies, 2020)
Vertical cavity surface emitting lasers (VCSELs) are now major optical sources in optical communication and
technology. The VCSEL-based transmission systems satisfy the next generation optical fibre access networks ...
Quasi-Particle Energy of a Mixture of Two-Component Gas of Bosons
(World Scientific News, 2020)
The properties of two component interacting gas of bosons are studied by assuming two slightly
different types of interactions between the atoms of the two gases. The system is described by two
operators a and b, that ...
INCOMMENSURATE CRYSTALLIZATION OF NEUTRON MATTER IN NEUTRON STARS
(EAST EUROPEAN JOURNAL OF PHYSICS, 2020)
The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One
can only surmise on the properties of neutron stars from the spectroscopic data ...
Analysis of CSRZ and CSNRZ Coding for DQPSK and OQPSK Transmitter Configurations for Optical Microwave Generation Signals Based on Stimulated Brillouin Scattering
(World Scientific News, 2020)
The use of Carrier Suppressed Non-Return to Zero (CSNRZ) and Carrier Suppressed Return to
Zero (CSRZ) modulation formats in Dense Wavelength Division Multiplexing (DWDM) channels at 1
Gb/s and 10 Gb/s is investigated. ...
Computation of the Expectation Value of the Electron – Phonon and Coulomb Interaction Hamiltonian using Second Quantization and Many Body Techniques
(International Journal of Research and Analytical Reviews (IJRAR), 2020-12)
The problem of the strong electron coupling in the theory of superconductivity has been discussed in many studies on the basis of electron and phonon spectral functions. For the rationale of investigating the effect of ...
Design of simultaneous multicolor coherent light generation in a single MgO:PPLN bulk crystal
(Journal of the Optical Society of America B, 2020-11)
We report on simultaneous sum-frequency mixing and doubling of C-band and 980 nm laser sources using a
single segmented periodically poled lithium niobate (PPLN) crystal in a single-pass configuration. Our theoretical
analysis ...
Landau Criteria of Superfluidity of Two Component Mixture of Bosons
(International Journal of Recent Research Aspects, 2020)
Using the quasi-particle energy of a mixture of two-component gas of bosons which is assumed to be in a
superfluid state, the Landau criterion for superfluidity has been applied to obtain the magnitude of the Landau’s ...
Frequency stability characterization: DFB laser and Raman pump performance on a distributed clock signal over 24.69 km fiber
(Journal of the Optical Society of America, 2020-07)
Distribution of timing and frequency signals in a fast-changing world requires unprecedented levels of stability for
characterization.Transfer of frequency references over long distance without introducing any additional ...
