Russia has developed material for photonic chips.
Russian scientists have created a metamaterial that is insensitive to internal defects. It acts as a unidirectional microwave lens and can be used in the production of photonic integrated circuits, which can become an alternative to conventional chips.
In the future it will be possible to use the development in microwave communication devices, antenna and radar systems. Photonic chips are also considered as a technology to accelerate data processing in data centers.
