Background:In order to maximize capacity carried in fiber-optic communication systems, spectrally efficient modulation formats are being intensely investigated. One such modulation format is called Nyquist-WDM (Wavelength Division Multiplexing) which results in a rectangular-like spectrum and concur.....

Infra-red (IR) imaging (in the LWIR and MWIR bands) is widely used for observation and surveillance applications. Most of IR optical materials are very sensitive to temperature changes. This sensitivity is reflected in a temperature dependent refractive index, that in turn it affects the focal lengt.....

Novel genetically modified crops resistant to environmental friendly herbicides.Weeds are considered to be one of the major causes for crop losses by farmers. It is estimated that weeds cause an overall 12% reduction in crop yields or $33 billion in lost crop annually. With the advent of biotechnolo.....
