| 英文摘要 | PURPOSE:To reduce the dispersion of coupling efficiency with an optical fiber by installing a lens holder having a lens to the upper section of a cap and forming inclined sections to the bottom of the cap and the outer circumferential section of a stem. CONSTITUTION:An inclined section 8 is shaped to the outer circumferential section of a stem 6 and an inclined section 9 to the bottom of a cap 7. A lens holder 4 with a lens 3 is placed to the upper section of the cap 7, the lens holder 4 of the upper section of the cap 7 is moved finely in the X and Y directions while an LD chip 1 is light-emitted, and an optical axis is aligned by a photo-detector mounted faced oppositely to the lens 3. When the optical axis is aligned, the lens holder 4 is fixed to the cap 7 through a solder material 5, etc., the inclined section 9 of the cap 7 is placed onto the inclined section 8 shaped to the outer circumferential section of the stem 6, welding is repeated step by step, and the cap 7 is moved finely in the direction of a Z axis and the optical axis is aligned in the Z direction. Accordingly, the dispersion of coupling efficiency with an optical fiber can be reduced. |
