英文摘要 | PURPOSE:To improve reliability under a high temperature condition by selecting a crystal wafer having the lattice constant ratio of active layer for substrate within the particular range to produce an element. CONSTITUTION:When lattice constants of a semiconductor substrate, semiconductor optical waveguide layer and semiconductor light emitting active layer are respectively set to a1, a2 and a3, these are in the following relationships, a1 |
