英文摘要 | PURPOSE:To increase coupling efficiency with an optical fiber by setting the height of a window area part higher by about 5mum than the upper part of an activation area. CONSTITUTION:Third and fourth semiconductor laminated bodies functioning as a window structure area against waveguide structure, and first and second reflection prevention film 11, 12 arranged at the end faces of the third and fourth semiconductor laminated bodies at sides opposite to that of first and second semiconductor laminate bodies out of the third and fourth semiconductor laminate bodies are provided. In such a case, respective area length of the third and fourth semiconductor laminated bodies is set at >=20mum, and also, the thickness of the laminated body is set higher by >=5mum compared with the position of an upper boundary between an activation layer and a clad layer. In such a manner, it is possible to improve the coupling efficiency with the optical fiber by 2.5dB/end face, and to acquire the improvement of 5dB in a gain between fibers. |
