FIBER OPTICS

EMCORE’s Model 3955 DFB laser in TO-can offers a low cost solution for linear

fiberoptic links. These components can be cooled with external thermo-electric

coolers for high stability, or run without TEC’s to reduce power consumption. The

DFB laser in TO-can builds upon Ortel’s long history of high performance, leading

edge designs in CATV, CWDM, wireless, and high speed digital applications. The

laser diode chip is mounted on a compact hermetic TO-can assembly together

with monitor photodiode and isolator, for flexible integration into the pigtail

package configuration.

Absolute Maximum Ratings¹

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.

Side Mode Suppression Ratio

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_OCvs. I_Fcurve (η₁, η₂, ... , η₅) 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.

3. Spectrum is measured using an optical spectrum analyzer with a spectral resolution better than 0.1 nm.
