Title: Semiconductor laser diode
Inventor: WATANABE HITOSHI
IPC: H01S5/00
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To maintain high slope efficiency and excellent current optical output characteristics and to increase the amount of chirping, by providing an active layer having a light emitting region between a p-side isolation sealing layer and an n-side isolation sealing layer, and making the thickness of the isolation sealing layer on the p-side thinner than the n-side. SOLUTION: The active layer having the quantum-well structure, where a well layer 4 and a barrier layer 5 are alternately laminated, is provided between an n-side isolation sealing layer (SCH layer) 2 and a p-side SCH layer 3. The p-side SCH layer 3 in the active layer is made thin in comparison with he n-side SCH layer 2. The leaking current to the thickness of the p-side SCH layer 3 becomes larger as the thickness of the layer becomes thick. Since it is better to decrease the leaking current to make the linearity of the optical output excellent, the p-side SCH layer 3 is made thinner in comparison with the n-side SCH layer 2. Therefore, the high slope efficiency is obtained, and the chirping amount can be made wide. Since a light emitting region is provided between the barrier layer and the well layer of the active layer, the laser oscillating efficiency can be made high.

Abstract: PURPOSE:To prepare rod steel and a wire material while shortening or omitting the spheroidizing treatment time of carbide, by a method wherein the temp. of steel of which the C-content is set to a predetermined value or less is raised by utilizing the processing heat generated, especially, during hot rolling and the heated steel is gradually cooled or held at a constant temp. CONSTITUTION:Steel containing 2% or less C is heated to a temp. ranging from 500 deg.C- a AC3 point and the heated steel is subjected to deformation by hot processing. In this case, plastic deformation of 10% or more is applied to said steel which is, in turn, heated to at least a temp. region of (AC1-100 deg.C) or more to generate deformation rupture of carbide and, thereafter, the dividing and spheroidizing of carbide are attained by C-diffusion. In the next step, the steel heated to the aforementioned temp. is cooled at a cooling speed of 100 deg.C/min or less through a temp. region reaching 500 deg.C to obtain rod steel or a wire material having the spheroidizing structure of carbide. In addition, by holding the steel for 7min or more in the aforementioned temp. region, carbide can be spheroidized effectively.
