| 摘要 | PURPOSE:To obtain a microminiature and inexpensive constant output semiconductor laser element by forming a semiconductor layer, a drive circuit, a light spectral analyzer and a light power detector on a ferrodielectric substrate for foring a photoconductive waveguide. CONSTITUTION:Partial step is formed on an insulating substrate 1, and a laser diode 2 is arranged. The laser output is led by a photoconductive waveguide 3 formed of a thin film into a light spectral analyzer 4. The waveguide 3 is formed by diffusing an impurity such as Ti in the substrate 1 of LiNbO3. Part of the laser output is fed through the waveguide to a photoreceptor 5 formed of a photodiode. The photoreceptor 5 transmits an electric signal is response to the received light amount to a controller 6 to control the laser output light to be always at constant level. The elements are formed by using a semiconductor IC manufacturing technique to determine the positions of the elements in high accuracy. |
| 其他摘要 | 目的：通过在铁电介质基板上形成半导体层，驱动电路，光谱分析仪和光功率检测器来获得微小且廉价的恒定输出半导体激光元件，以便形成光电导波导。组成：在绝缘基板1上形成部分台阶，并设置激光二极管2。激光输出由由薄膜形成的光电导波导3引导到光谱分析仪4中。波导3通过在LiNbO3的衬底1中扩散诸如Ti的杂质而形成。部分激光输出通过波导馈送到由光电二极管形成的感光器5。感光器5将对接收到的光量的响应的电信号发送到控制器6，以控制激光输出光始终处于恒定水平。通过使用半导体IC制造技术以高精度确定元件的位置来形成元件。 |
