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。

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.

摘要： This invention relates to a semiconductor laser of a buried-hetero structure. In this semiconductor laser, the side surfaces of an active layer are in contact with a plane having a stable state of interface. As a result, the threshold current value of this semiconductor laser is low, and a stable operation can be obtained without causing any kink (projection) in the current-optical output characteristics. An optical communication system using this semiconductor layer has a low operating current, and can maintain high coupling efficiency with an optical fiber without the occurrence of noise, so that optical communication having high reliability is possible.

摘要： An optical transmission device obtains driving control data corresponding to a temperature detected by a temperature detection circuit (112) from memory means (173), controls a driving current to be supplied to a laser diode (100) based on the driving control data, and measures a driving current to be actually supplied to the laser diode whose emission power is held constant by an automatic optical output control circuit (115, 113). Further, when the difference between the measured driving current and a driving current determined by the driving control data corresponding to the detected temperature at that time exceeds an allowable range, the optical transmission device updates the driving control data related to the corresponding temperature, on the memory means so that the difference between the driving currents is defined as each of increases in bias current and modulating current.

Further, when the difference between the measured driving current and a driving current determined by the driving control data corresponding to the detected temperature at that time exceeds an allowable range, the optical transmission device updates the driving control data. Upon determination of the deterioration of the laser diode, the progress of the deterioration of the laser diode is determined based on the difference between a driving current defined by driving control data corresponding to a newly measured temperature and an actual driving current formed by automatic optical output control. Therefore, a distinction between whether an increase in driving current due to the automatic optical output control results from the deterioration of the laser diode and whether it results from a variation in ambient temperature is reliably made.

摘要： In a polarization dependency type optical isolator comprising wedgelike polarizing prisms 3 and 5 and a Faraday rotator 4, the mode field diameters of an input side fiber 1 and an output side fiber 7 are the same as that of a transmission fiber and an erbium-doped fiber to be connected to them. The shape and other features of each lens are controlled so that the spot size of a parallel ray which is converted from an incident ray by an input side lens 2 is equal to the spot size of a parallel ray which is converted by an output side lens 6 when a reference beam is irradiated from the fiber 7. In a rare-earth-doped fiber optical amplifier using an optical isolator which is configured in a manner similar to this, the connecting portion of the fiber and the optical isolator can be spliced by fusion without increasing the insertion loss of the optical isolator in the forward direction and the connection loss due to a difference in the mode field diameter is reduced. Therefore, the noise figure decreases and the gain increases.
