摘要： A monitoring and control assembly for an optical system includes a tunable laser. The laser generates a divergent output beam along an optical axis. A first photodetector is provided. A wavelength selective filter is tilted at an angle relative to the optical axis that provides an angular dependence of a wavelength reflection of the wavelength selective filter and directs the reflected output beam towards the first photodetector.

摘要： A multiplexer for a wavelength division multiplexed optical communication system includes an optical circulator with at least first, second, third and fourth circulator ports. An optical fiber with a first optical transmission path is coupled to the first circulator port and carries a wavelength division multiplexed optical signal that includes signals 1−n. A second optical transmission path is in optical communication with the second circulator port. A first laser is coupled to the second optical transmission path. The first laser reflects the 1−n signals and adds a signal n+1. A control loop is coupled to the first laser. In response to a detected change in temperature the control loop sends a signal to adjust a voltage or current supplied to the first laser and provide a controlled frequency and power of an output beam. A third optical transmission path is in optical communication with the third circulator port and transmits the signals 1−n and the signals n+1 that are received from the optical circulator. A fourth optical transmission path is in optical communication with the fourth optical circulator port. The fourth optical transmission path is positioned after the second optical transmission path and before the third optical transmission path. A first optoelectronic device is coupled to the fourth optical transmission path.

摘要： A tunable semiconductor laser system includes a laser with a semiconductor active region positioned between upper and lower confining regions of opposite type semiconductor material. First and second reflective members are positioned at opposing edges of the active and confining regions. A wavelength tuning member and a temperature sensor are coupled to the laser. A control loop is coupled to the temperature sensor and the tuning member. In response to a detected change in temperature the control loop sends an adjustment signal to the tuning member and the tuning member adjusts a voltage or current supplied to the laser to provide a controlled output beam of selected wavelength.

A temperature sensor coupled to the laser. A control loop is coupled to the temperature sensor and the tuning member.
