Compact lasers to replace copper to cope future microchip processing speed

With every passing day, technology seems to evolve several times. The booming microchip-processing speed is rejuvenating the different areas of an integrated circuit. But, the present use of the tiny copper wires is hindering this happening segment of the microelectronics industry. The European researchers have eventually come up as an answer to this. They have developed technologies that can only produce, but also combine semiconductor micro-lasers with silicon wave guides to given birth to, importantly, power-efficient optical connections.

The researchers’ new method can etch indium-phosphate lasers with a diameter of just 7μm! Ah! This is sufficiently small to integrate several thousand onto a 2cm x 2cm silicon chip -- producing such compact lasers for the first time in a very practical as well as a cost-efficient way. These tiny lasers could also be applied in miniature optical sensors or be used in building incredibly cheap optical biosensors, which would also be, very powerful.

With copper’s inability to cope with the future microchips’ processing power, this development is surely the biggest breakthrough –- the bonding technology -- joining together the silicon and iridium-phosphate materials.
