Abstract
Green light emitting diodes (LED) of gallium arsenide (GaAs) are series-connected. The series connection has a small transmission attenuation and a wide bandwidth. The GaAs LED has a big forward bias and so neither extra driving current nor complex resonant-cavity epitaxy layer is needed. Hence, the present invention has a high velocity, a high efficiency and a high power while an uneven current distribution is avoided.
