Abstract: PURPOSE:To obtain a semiconductor optical amplification element whose polarization plane dependence is small by a method wherein a beam is incident from a plane direction of an active Iayer, is reflected in a multiple manner between one pair of reflecting surfaces formed so as to sandwich the active layer and is amplified. CONSTITUTION:An incident beam Pin is incident at an angle of thetao from a region where an antireflection film 10 has been formed and it repeats multiple reflection in a zigzag manner between light reflecting surfaces 7, 9 which function also as electrodes. At the same time, at each reflecting operation the beam passes through an active iayer having a gain by injection of a carrier. As a result, it is amplified and is radiated as a radiation beam Pout from a region where an antireflection film 10' has been formed. During this process, the propagating beam passes through a plane of the active layer 4 nearly vertically when the incidence angle thetao is selected to be small to a certain extent. By this setup, it is possible to nearly eliminate the polarization plane dependence on an amplification factor.
