Researchers in France have made the first ultra-compact laser diode that can be integrated with silicon photonic waveguides without losing its light-emitting efficiency. The device, which works at the important telecommunications wavelength of 1.56 µm, could be used for constructing optical networks at the sub-millimetre scale for intra-chip optical interconnects and signal processing……
