The JDSU 2700 Series of 980 nm pump modules utilizes a planar construction with chip on subcarrier. The high power JDSU laser chip is hermetically sealed in a low-profile, epoxy-free and flux-free 14-pin butterfly package, fitted with a thermistor, thermoelectric cooler, and monitor diode. The module meets the stringent requirements of the telecommunications industry, including TelcordiaTM GR-468-CORE for hermetic 980 nm pump modules. The 2700 Series pump module uses fiber Bragg grating stabilization to "lock" the emission wavelength and 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.
