Title: Semiconductor laser element
Inventor: HOSODA MASAHIRO
IPC: H01S5/00
Filed: 1987-05-19
Abstract: PURPOSE:To suppress growth of a buried layer on a mesa part for obtaining an element having a low threshold value current and oscillating in a lateral mode, by forming a protective layer on the surface of the mesa part of an index guide type element of Ga1-xAlxAs (x>zero). CONSTITUTION:A current blocking layer 2 is made to grow on a substrate 1 by a liquid phase epitaxial (LPE) method followed by forming a V-groove part 10. Next, a clad layer 3, an active layer 4, a clad layer 5, and a Ga1-xAlxAs protective layer 6a are laminated by turns by the LPE growth. Later, the regions excepting the V-groove parts 10 of each layer from the layer 6a to the layer 3 are etched to form a mesa part 11. Further, a high resistance buried layer 7 and a buried layer 8 are laminated on a layer 2 in the regions on both sides of the mesa part 11 by the LPE growth. At this time, the surface of the mesa part 11 has an exposed crystal containing Al of the layer 6 so as to suppress the growth. Accordingly, sufficiently thick buried layers can be formed on both sides of the mesa part 11 so as to reduce a leakage current and enable a stable lateral mode oscillation of low threshold value current.

Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a thin film having high conductivity, capable of effectively exerting a leakage electromagnetic wave shielding effect, having a high total light transmission factor, generating no moire interference pattern, and usable as an electrode at a low cost by forming it with a fine mesh structure made of silver. SOLUTION: This transparent conductive film is made of a metal having low volumetric specific resistance, particularly silver, into a fine mesh structure, and it has a high light transmission factor while maintaining high conductivity. When the average opening diameter of meshes exceeds 50 μm in the transparent conductive film having the fine mesh structure, the mesh structure can be recognized via naked eyes, visibility becomes inferior, therefore the average opening diameter is set to 50 μm or below. When the average opening diameter/average line width is smaller than 7, the area of the opening portion becomes relatively narrow, the total light transmission factor of 60% or above is difficult to secure, therefore the average opening diameter/average line width is set to 7 or above.
