The search for a structure that blocks the passage of light in all directions has fascinated physicists and engineers for the past two decades.

Controlled light can be directed, switched and processed like electrons in an electronic circuit, and such photonic devices have many applications in research and in communications.

Even the straightest path has two directions.

There are many possible directions to go from here. The current structure is folded only once. Like paper origami, it is possible to fold multiple times.

he turns to the sunlight,
And lifts her face up,
She searches for the light,
The light of hope, the light to kill her darkness
She is broken inside, has lost her hope to revive,
It’s all dark even in the brightest of daylight,
She was living with the hurricane eyes all her life
But today, the storm has hit high,
Touching her face, blowing her mind,
Whispering into her subconscious mind,
And as the lamp comes to her sight,
She finds the real source of light,
Gathering all broken pieces to survive,
The light she was searching for has always been inside.
Because she has always been the star wrapped in the skin of life!! ~AB

The pattern in which photons are blocked or not blocked had never really been computed. In the laboratory, we were able to construct a device that was effectively like doing a computer simulation to see the patterns of transmission.
