Operating wavelength range of the detector is from 6 to 100 nm.
The presented simulations are performed over a spectrum of 800 830 nm to cover our operating wavelength of 813 nm, where the mode size has a very moderate change with wavelength.
Yet even the largest antennas, when used at their shortest operating wavelength, have an angular resolution of only a few arc seconds, which is about 10 times poorer than the resolution of ground-based optical telescopes.
With the metal disks being periodically staggered on both sides of a dielectric layer, there is a great improvement of the transmission efficiency at a specific operating wavelength.
The performance parameters of the proposed sensor are investigated in terms of sensitivity, detection accuracy and quality factor at operating wavelength of 633 nm.
Calculation results show that the efficiency of 100% and quality factor of nearly 1500 at operating wavelength of 1550 nm can be achieved.
It is found that no appreciable change in image quality under diffraction-limited condition results for an input beam having 632 nm operating wavelength and 60 nm bandwidth.
The equidistance picometric spectral shifts corresponding to each measurands over the operating wavelength of 1550 nm are observed and is suitable for detection of graphene and graphene oxide.
The relationships among the V parameter, confinement loss, relative sensitivity, operating wavelength and structural parameters of microstructured optical fibers for gas sensing applications are investigated theoretically.
The dispersion characteristic has also been analyzed with respect to wavelength, which is nearly 2.5 ps/nm km at operating wavelength 1550 nm.
At 1.55 μm operating wavelength, the value of nonlinear coefficient is 1179 W−1 km−1 and dispersion ∼41 ps/nm-km.
