The JDSU 2600-TE Series 980 nm pump module utilizes a planar construction with chip on subcarrier. The high power JDSU laser chip is hermetically sealed in a low-profile, epoxy- and flux-free 14-pin butterfly package and 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 2600-TE Series pump module uses fiber Bragg grating stabilization to "lock" the emission wavelength. It provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers. The 2600-TE Series design also offers tight tracking of fiber-coupled power via the monitor diode signal.
