In today's world, when scientists are constantly studying large-scale integrated circuits, they find that due to the characteristics of electrons,

The integration of semiconductor devices is approaching the limit,

Photons have superior characteristics that electrons don't have:

The transmission speed is fast,

No interaction.

So scientists hope to get new materials,

It's like controlling electrons in a semiconductor.

Similarly,

Free control of photons,

Namely photonic crystals.

With the development of science and technology, especially manufacturing technology

The development of,

Making the fabrication of photonic crystals not only possible,

And made great progress,

In visible light and

The infrared band can be made into photonic crystals with required energy band structure,

Realize the control of photons.

In order to study the energy band of one-dimensional photonic crystals,

In-depth study of forbidden zones,

This is very important for the design and preparation of one-dimensional photonic crystals.

Very educational.

In this paper, the theory of thin film optics is put forward,

Propagation analysis of light wave in one-dimensional photonic crystal

Features,

The refractive index of photonic crystal films is discussed.

Number of cycles,

Optical Band Gap of One-dimensional Photonic Crystals with Equal Central Wavelength

Performance, so as to provide reference for the design of one-dimensional photonic crystals.
