英文摘要 | PURPOSE:To obtain a semiconductor laser, which conducts longitudinal single mode oscillation by low threshold currents and has excellent optical output- current characteristics and in which there is no turbulence of a transverse mode extending over a wide operating current range, by forming a trench being shaped to a semiconductor thin-film epitaxial-grown onto a semiconductor substrate and periodically meandering while keeping predetermined trench width, a clad layer formed into the trench and an active layer. CONSTITUTION:P-InP 2, n-InP 3 and n-InGaAsP 4 are grown by an epitaxial method onto an InP substrate An SiO2 thin-film is shaped onto the surface of n-InGaAsP 4, and a resist is applied. A meandering trench is formed through a photolithographic technique, and a meandering trench is also shaped to SiO2, using the trench as a mask. When a meandering period is brought to 3.8mum, twenty times as long as half a wavelength, in the case of a 3mum band laser employing InGaAsP as an active layer, a pattern can be shaped sufficiently through the photolithographic technique. Accordingly, an n-InP layer 6 as a clad layer, a p-InP layer 7 and an n-InGaAsP layer 8 as the active layer are buried and grown into the formed meandering trench 5. |
