A ideia de utilizar feixes laser em vez de pistas de cobre, para permitir a comunicação entre os componentes de um computador não é nova, o que tem levado muitas empresas a dedicar algum do seu precioso tempo a este conceito.
Mas a HP pretende ser pioneira e como poderão ver na imagem acima, está a desenvolver um “dispositivo de microanel fotónico”, que é parte da arquitetura do chip fotónico chamado Corona.
O Corona é um chip fotónico integrado 3D, que integra 256 núcleos para funções gerais, organizados em 64 grupos de quatro núcleos cada. Este processador beneficia de uma enorme quantidade núcleos, contudo, a sua rapidez deve-se essencialmente à interligação ótica (com ligações laser) ente componentes.
Cada núcleo poderá comunicar entre si, a uma velocidade de 20 terabytes por segundo, com a memória em loop a 10 terabytes por segundo, efetuando umas impressionantes 10 biliões de operações de ponto flutuante por segundo.
Tudo isto num único chip, que multiplicado por centenas ou mesmo milhares destes processadores fotónicos, integrados num supercomputador, permitirá atingir velocidades de mil milhões de gigahertzs. O que seria impossível com um chip não ótico.
A eficiência é outra das vantagens dos chips fotónicos. Usar electricidade para transmitir 10 terabytes por segundo, entre a CPU e a memória externa requer 160 watts de potência, enquanto a HP Labs calculou que usar um chip fotónico integrado requer apenas, 6.4 watts de potência.
Isto significa que os processadores ópticos serão 25 vezes mais eficientes do que os processadores comuns e com um pouco de sorte, esta tecnologia poderá estar disponível dentro de 3 a 5 anos.

But HP intends to be a pioneer and as you can see in the picture above, is developing a "device microanel photon", which is part of the photonic chip architecture called Corona.
The Corona is a 3D integrated photonic chip, which integrates 256 cores for general functions, organized into 64 groups of four cores each. This processor has a huge amount nuclei, however, its speed is mainly due to the optical interconnection (with laser links) among components.
Each core can communicate with each other at a speed of 20 terabytes per second, with the memory loop 10 terabytes per second, performing an impressive 10 billion floating point operations per second.
All this in a single chip, which multiplied by hundreds or even thousands of processors photonic integrated into a supercomputer, will reach speeds of gigahertzs billion. What is impossible with a non-optical chip.
Efficiency is another advantage of photonic chips. Using electricity to transmit 10 terabytes per second, between the CPU and external memory requires 160 watts of power, while HP Labs has calculated that using a photonic integrated chip requires only 6.4 watts of power.
This means that the optical processors will be 25 times more efficient than the standard processors and with some sort, this technology may be available within 3-5 years.
