Lumics intros uncooled pump module

Fiber Optics Weekly Update, Sept 13, 2002

Lumics a manufacturer of pump laser modules and laser chips, announced a line of coolerless 980nm pump laser modules. The new product is based on Lumics propriety chip technology. The LU0980M1402 pump laser module operates without a thermoelectric cooler over a broad temperature range. Uncooled operation greatly reduces the total power consumption of the pump laser module. The new module uses a very small Mini-DIL package platform to operate over 0 to 70 C temperature range. The package footprint is just 7 x 13mm with a maximum height of 5mm.

The coolerless modules are designed for use in fiber amplifiers deployed in high-speed optical telecommunications networks. Mini-DIL pump lasers will enable a significant reduction in the size and power consumption of EDFAs used in metro and long haul optical systems

The Mini-DIL pump LU0980M1402 offers 140mW operating power at a significantly lower price point and reduced form factor compared to conventional pump packages. The pump performance over the 0-70[degrees]C temperature range is maintained by fiber Bragg grating (FBG) wavelength locking.
