Dielectric Constant of Silicon and Silicon Dioxide¶

Getting Started¶

Dielectric constant (permittivity) of specified materials. (Si/SiO2)

• It takes 1 argument which is wavelength in micron.
• Similar to effective index function, wavelength range is between 1.2 - 1.7 microns.

Arguments:

• wavelength (float): wavelength in micron, range 1.2 - 1.7

Returns:

• permittivity (float): permittivity of specified material

See dielectric constant of Silicon at wavelength 1.55 micron:

In [ ]:

import sipkit

print(sipkit.perm_si(1.55))

import sipkit print(sipkit.perm_si(1.55))

Below code returns dielectric constant of Silicon Dioxide at wavelength 1.55 micron:

In [ ]:

print(sipkit.perm_oxide(1.55))

print(sipkit.perm_oxide(1.55))

Exceptions¶

Unless the first argument is between 1200 - 1700 nm, it will raise an exception.

In [ ]:

print(sipkit.perm_oxide(1.15))

print(sipkit.perm_oxide(1.15))

In [ ]:

print(sipkit.perm_oxide(1.823))

print(sipkit.perm_oxide(1.823))
