Sentence examples for multiple defect modes from inspiring English sources

In addition, by increasing the repeated number Np, we can have multiple defect modes, leading to a possible design of tunable multichannel filter.

Finally, by increasing the defect thickness leads to the presence of multiple defect modes which can be used to design a multichanneled filter.

We report the existence of multiple omnidirectional defect modes in the zero-¯n gap of photonic stacks, made of alternate layers of conventional dielectric and double-negative metamaterial, with a polaritonic defect layer.

For both cases of square defect or circular defect, the defect modes vary obviously as the shape of the defect body only for a bigger defect filling fraction.

Besides, stopband can be greatly widened with multiple defect cavities.

We therefore investigate the stability of nonlinear defect modes.

The grading profiles of the defect layer affect the frequency and intensity of photonic defect modes.

Localized defects in the periodic structure give rise to defect modes, which persist as nonlinear defect modes as the amplitude is increased.

Since the defect cavity works differently when they are located at different sites, we further propose multiple defect cavities.

The properties of defect modes in one-dimensional photonic crystals (PCs) containing a graded defect layer are studied theoretically.

Therefore, introducing a graded defect layer in one-dimensional PCs provides possible mechanism for tuning the defect modes.
