    • A laser diode module includes a laser diode device, a first photo detector part for receiving, first divided light that is a first portion of light when at least one of light emissions of the laser diode device is divided into two portions of light each traveling a different optical path, a second photo detector part for receiving second divided light that is a second portion of light thus divided via at least a wavelength selective member, and a controller which controls the lasing wavelength of the laser diode device on the basis of outputs of the first and second photo detector parts. A beam splitter provided between the laser diode and the wavelength selective member divides light emitted from the laser diode into the first and second divided light and a quarter-wave plate is provided in an optical path between the beam splitter and the wavelength selective member.

    • To resolve a problem in which in an optical output and wavelength monitor integrated type semiconductor laser module monolithically integrated in parallel with a plurality of semiconductor lasers, since light emitting positions of the respective semiconductor lasers differ, an allowable range of an optical incident position of the monitor is exceeded, the optical incident position of the monitor is confined in the allowable range by integrating backward optical waveguides for guiding backward beam of the respective semiconductor lasers to a narrow range at a backward end of a semiconductor chip along with the semiconductor lasers, whereby there can be easily realized a semiconductor laser module with a built-in optical monitor even in the case of the chip integrated with the plurality of semiconductor lasers and can be realized an inexpensive optical module having high function.
    • 为了解决在与多个半导体激光器并联地单片集成的光输出和波长监视器集成型半导体激光器模块中的问题,由于各个半导体激光器的发光位置不同,所以光入射位置的允许范围 监视器被超过,通过将反射光波导集成在半导体激光器的半导体芯片的后端,将各个半导体激光器的反向光束集成到窄范围内,将监视器的光学入射位置限制在允许范围内,由此 即使在与多个半导体激光器集成的芯片的情况下,也可以容易地实现具有内置光学监视器的半导体激光器模块,并且可以实现具有高功能的便宜的光学模块。
