摘要	PURPOSE:To enable to oscillate at single spectrum even when a direct modulation by current is performed by a method wherein one end face of optical fiber is coupled to the end face of one resonator of a semiconductor laser, and the other end face of the optical fiber is coupled to the other end face of the semiconductor laser. CONSTITUTION:The branching device 6 inserted in the middle of optical fiber branches a part of light in such a manner that it is picked out to outside. A mount 7 is used to fix a semiconductor laser chip and optical fiber 5, and the semiconductor chip is adhered to the mount 7 by solder. An electrode 8 is attached to the upper surface of the semiconductor laser chip and it is connected to a power source. The center part of one end face of the optical fiber is accurately positioned on the oscillation part of the semiconductor laser, and it is fixed to the mount. The other end face of the optical fiber is fixed in such a manner that it is coupled to the other oscillation part of the semiconductor laser in the same manner as above. The resonator of the semiconductor laser itself and the resonator composed of the optical fiber constitute a composite resonator, and a single wavelength can be oscillated in a selective manner.
其他摘要	用途：即使通过光纤的一个端面耦合到半导体激光器的一个谐振器的端面和光学的另一个端面的方法进行电流直接调制，也能够在单个光谱上振荡光纤耦合到半导体激光器的另一个端面。组成：插入光纤中间的分支设备6分支一部分光，使其被挑选到外面。支架7用于固定半导体激光器芯片和光纤5，并且半导体芯片通过焊料粘附到支架7。电极8附着到半导体激光器芯片的上表面并且连接到电源。光纤的一个端面的中心部分精确地定位在半导体激光器的振荡部分上，并且固定到安装件。光纤的另一个端面以这样的方式固定，即它以与上述相同的方式耦合到半导体激光器的另一个振荡部分。半导体激光器本身的谐振器和由光纤构成的谐振器构成复合谐振器，并且可以选择性地振荡单个波长。
