英文摘要 | PURPOSE:To obtain a semiconductor laser producing low noise by sequentially laminating a first clad layer, an active layer, an optical guide layer and a second clad layer and forming a current blocking layer on the side face of the second clad layer. CONSTITUTION:A first clad layer 2, an active layer 3 having smaller band gap than that of the layer 2, an optical guide layer 4, and a second clad layer 5 having a stripelike mesa structure of an inverted trapezoidal shape of section state are sequentially laminated. Further, a current block layer 7 for absorbing a light generated at the active layer is formed on the side face (mesa side face) of the clad layer 5. Thus, even if a high frequency superposing system is not employed, a semiconductor laser producing low noise can be obtained. |
