s Highly ef?cient DFB-MQW laser structure allows for lower threshold and drive currents, and reduced power consumption

Description

The D371-Type Uncooled Laser Module consists of a laser diode coupled to a single-mode ?ber pigtail. The device is available in a standard, 8-pin con?g-uration (see Figure 1 and/or Table 1) and is ideal for long-reach (SONET) and other high-speed digital applications.

The laser diode is a narrow linewidth (<1 nm) DFB-MQW single-mode laser and an InGaAs PIN photo-diode back-facet monitor in an epoxy-free, hermeti-cally sealed package.

Description (continued)

The device characteristics listed in this document are met at 2.0 mW output power. Higher- or lower-power operation is possible. Under conditions of a ?xed pho-todiode current, the change in optical output is typically ± 0.5 dB over an operating temperature range of –40 ° C to +85 ° C.

This device incorporates the new Laser 2000 manufac-turing process developed by the Optoelectronic unit of Agere Systems Inc. Laser 2000 is a low-cost platform that targets high-volume manufacturing and tighter product distributions on all optical subassemblies. The platform incorporates an advanced optical design that is produced on a highly automated production line. The Laser 2000 platform is quali?ed for the central of?ce and uncontrolled environments, and can be used for applications requiring high performance and low cost.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

* Rating varies with temperature.
