英文摘要 | PURPOSE:To accurately and easily measure the far field pattern characteristics of a semiconductor laser by positioning the semiconductor laser and a photodetector optically. CONSTITUTION:A measuring instrument capable of measuring the far field pattern characteristics of the laser detects position shifts between semiconductor lasers 1-3 and a photodetector (photosensor) 4. Then the semiconductor lasers 1-3 are positioned by being moved in a 1st or 2nd direction in hetero-junction surfaces of the semiconductor lasers 1-3 relatively to the photosensor 4. Then, while the photosensor 4 rotated around 1st and 2nd directions relatively to the semiconductor lasers 1-3, a rotational angle-light quantity distribution is measured. Data regarding respective measured characteristics are processed properly and statistically together with temperature conditions and outputted on a CRT. Consequently, the far field pattern characteristics of the semiconductor lasers can be measured. |
