The JDSU 2745 series of 980 nm pump modules uses a planar construction with chip on subcarrier. The `semicooled' 45C laser diode operation provides for a significant reduction in TEC and overall power consumption. The high-power JDSU laser chip is hermetically sealed in a low-profile, 14-pin butterfly package, fitted with a thermistor, thermoelectric cooler, and monitor diode. The module meets the stringent requirements of the telecommunications industry, including Telcordia GR-468-CORE for hermetic 980 nm pump modules. The 2745 series pump module, which uses fiber Bragg grating stabilization to lock the emission wavelength, provides a noise-free, narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications requiring the highest performance in spectrum control with the highest powers available.
