摘要： An embodiment of the invention relates to a cascade semiconductor light source comprising:a first block of cascades and a first contact region coupled to said first cascade, the first contact region being capable of injecting carriers into the first cascade of the first block; anda second block of cascades and a second contact region coupled to said second cascade, the second contact region being capable of injecting carriers into the second cascade;wherein the application of a first polarity voltage to said light source results in the cascades in the first block to be in an active mode and the cascades in the second block to be in an inactive mode;wherein the application of a second, opposite polarity voltage to said light source results in the cascades in the first block to be in an inactive mode and the cascades in the second block to be in an active mode;wherein the first block of cascades is adapted to emit light at a first wavelength in its active mode and to passively conduct electrical current in its inactive mode; and wherein the second block of cascades is adapted to emit light at a second wavelength in its active mode and to passively conduct electrical current in its inactive mode.
