A quantum leap in laser emission

Medium- and long-haul, high-speed fiber communication systems are dominated by the need for low optical loss and low dispersion, and these systems require laser diodes and photodiodes that emit and detect at 1.33 and 1.55 μm. InGaAs/GaAs quantum dots enable 1.3 μm wavelengths in GaAs-based lasers for fiber-optic communication
