英文摘要 | PURPOSE:To reduce an oscillation threshold current and an astigmatic difference by specifying the relationship of the widths of the ridges of an emitting end face region and a selfexcited oscillation region, and the relationship of the thicknesses of an optical guide layer and a clad layer in a region except the ridges of the emitting end face region and the self-excited oscillation region. CONSTITUTION:The width W2 of a current injection path 12 of one end face near region 14 and the width W1 of the current injection path 12 of a region 13 except the region satisfy the relationship of 5W1d2. In this case, loss due to the difference of light modes of the self-excited oscillation region 13 and the emitting end face region 14 is almost eliminated. Thus, an astigmatic difference can be reduced whole the oscillation threshold current is maintained small. |
