摘要： A semiconductor laser device is formed of a semiconductor material assembly including a first semiconductor layer having an active region formed directly by crystal growth on a substrate for the crystal growth having on the surface thereof a second semiconductor layer. A third semiconductor layer is also formed on the first layer. The refractive index of each of the second semiconductor material region and the third semiconductor layer is smaller than that of the first semiconductor layer while the band gap of each of the second semiconductor material region and the third semiconductor layer is broader than that of the first semiconductor layer. In order to provide mode stabilization even at long wavelength, the thickness of the active region formed at the interface between said first semiconductor layer and said substrate for crystal growth is made larger than the thickness of the other portions in the first semiconductor layer so that the effective refractive index to laser beams is changed stepwise in a direction perpendicular to the direction of the laser beams.

摘要： In a photoelectric device, particularly, a photoelectric device for optical communication, an optical fiber is fixed at two fixing points so that the extremity of the optical fiber is disposed opposite to the light emitting surface of a laser diode chip and the optical fiber extends in a nonlinear shape, for example, in a moderate curve, between the two fixing points. Even though holding members fixedly holding the optical fiber at the two fixing points and a base member supporting the holding members are formed of a metal or metals having a coefficient of thermal expansion far greater than that of the optical fiber, and even if the distance between the two fixing points is varied due to the thermal expansion or contraction of the holding members and the base member, the optical fiber is obliged only to change the shape of extension. Therefore, the optical fiber and the solder fixing the optical fiber to the holding members at the two fixing points are not subjected to repeated stress, and hence the fatigue of the optical fiber and the solder is avoided. Accordingly, the photoelectric device is able to continue stable optical communication regardless of temperature variation.
摘要翻译：在光电装置中，特别是光通信用光电装置中，将光纤固定在两个固定点，使得光纤的末端与激光二极管芯片的发光面相对配置，并且光纤延伸在在两个固定点之间的非线性形状，例如以中等曲线。即使固定部件将光纤固定地保持在两个固定点，并且支撑保持部件的基部构件由热膨胀系数远大于光纤的热膨胀系数的金属或金属形成，并且即使两个固定点由于保持构件和基底构件的热膨胀或收缩而变化，因此光纤仅需要改变延伸的形状。因此，在两个固定点处将光纤固定到保持构件上的光纤和焊料不会受到重复的应力，因此避免了光纤和焊料的疲劳。因此，无论温度变化如何，光电装置能够持续稳定的光通信。

Therefore, the optical fiber and the solder fixing the optical fiber to the holding members at the two fixing points are not subjected to repeated stress, and hence the fatigue of the optical fiber and the solder is avoided. Accordingly, the photoelectric device is able to continue stable optical communication regardless of temperature variation. Terminals are formed by leads having an inductance reducing thick portion that are connected to the photoelectric device inside a box-shaped housing. A thinner lead conforming to the prevailing standard connector is connected to the thick lead using ultrasonic bonding at a position outside of the housing.
