英文摘要PURPOSE:To make a coupling coefficient kappa small by a method wherein a first guide layer having a diffraction grating is so formed as to have a low refractive index, a difference in the refractive index between this layer and a clad layer is made small, a second guide layer is provided on the opposite side thereto, a power distribution of light is drawn onto the second guide layer side and the coupling of light with the diffraction grating is made small. CONSTITUTION:An InP clad layer 2 of a band gap width Ec, a second InGaAsP guide layer 3 of the width Eg2, an InGaAsP active layer 4 of Ea, a first InGaAsP guide layer 5 of Eg1 and an InP clad layer 6 of Ec and an InCaAsP contact layer are laminated sequentially on an InP substrate The band gap widths Ea, Eg1, Eg2 and Ec are so set that the relationship of Ea
