Hybrid Silicon Laser

As silicon transistors get smaller and faster, the bottleneck of the IC boils down to interconnects which traditionally use copper or aluminum wires with limited speed and bandwidth. Silicon-based optoelectronic integration offers the promise of low-cost solutions for optical communications and interconnects. A major advance in this field is the use of III–V lasers bonded on silicon and coupled to silicon waveguides. Such an approach is called hybrid integration and lasers built using such this approach are called hybrid silicon lasers.
