data sheet A370-type analog uncooled fastlight laser module january 1999 2 2 lucent technologies inc. description the A370-type uncooled laser module consists of a laser diode coupled to a single-mode ?er pigtail. the device is available in a standard, 8-pin con?uration (see figure 1 and/or table 1) and is ideal for catv applications. the module includes a multiquantum-well fabry-perot (mqw f-p) laser and an ingaas pin photodiode back- facet monitor in an epoxy-free, hermetically sealed package. the device characteristics listed in this document are met at 1.0 mw output power. higher- or lower-power operation is possible. under conditions of a ?ed pho- todiode current, the change in optical output is typically 0.5 db over an operating temperature range of ?0 c to +85 c. this device incorporates the new laser 2000 manufac- turing process from the optoelectronics unit of lucent technologies microelectronics group. laser 2000 is a low-cost platform that targets high-volume manufactur- ing and tight product distributions on all optical subas- semblies. this platform incorporates an advanced optical design that is produced on the optoelectronic unit s highly automated production lines. the laser 2000 platform is quali?d for the central of?e and uncontrolled environments, and can be used for appli- cations requiring high performance and low cost. figure 1.
