EMCORE CORPORATION
Model 3933 DFB 1310 nm Laser in TO-can
Absolute Maximum Ratings
1
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are
absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in
excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for
extended periods can adversely affect device reliability.

Absolute maximum data are limited to system design only; proper device performance is not guaranteed over rating listed above. Operation
beyond these maximum conditions may degrade device performance, lead to device failure, shorter lifetime, and will invalidate the device
warranty.

Notes:
1. Slope efficiency is measured in a current range between I
th
+ 5 mA and I
th
+ 65 mA.
2. Linearity is calculated by first determining slopes of five sequential pairs of points along the linear portion of the P
OC

) in the drive current range (30mA and 80 mA). The difference between the maximum and minimum of these slopes
divided by the slope efficiency (defined as the slope of linear regression) defines Linearity.
