The expression for waveguide parameter

V

is given as follows:

V=\frac{2 \pi}{\lambda_{0}} d \sqrt{n_{1}^{2}-n_{2}^{2}}

Here,

d

is the width,

\lambda_{0}

is the operational wavelength,

n_{1}

and

n_{2}

are the indexes of refractions. Substitute

n_{1}=1.50

n_{2}=1.46

\lambda_{0}=0.6328 \ \mu \mathrm{~m}

, and

d=4 \ \mu \mathrm{~m}

to calculate

V
