Abstract

PURPOSE:To enhance the efficiency of a light emitting device by forming active layer, third, first and second semiconductor layers having smaller energy gap than the semiconductor layer on the semiconductor layer and increasing the energy gap of the third semiconductor layer than the first semiconductor layer. CONSTITUTION:Active layer 2, third, first and second semiconductor layers 3, 4, 5 having smaller energy gap than a semiconductor layer 1 are formed on the layer 1. There are also formed the first semiconductor layer having a energy gap corresponding to the 1/2 wavelength of the emitted light of the layer 2 and the second semiconductor layer having energy gap adjacent to the first layer. The energy gap of the third layer varied with the lattice constant is increased larger than the first layer. In this manner, secondary harmonic light can be efficiently.
