The laser products are  InGaAsP/InP based DFB LD for Methane sensing applications.These chips are processed using RWG technology.The facets are coated with an anti-reflectance coating on the front facet and a  high reflectance coating on the rear facet.All laser chips come from wafers that have been certified using a representative lot of chips that must achieve an acceptable yield for chip test and dynamic test and Burn-in.

*Parameters are tested at 25℃ unless otherwise specified. 

**λo = absorption peak  wavelength@65℃

Absolute Maximum Ratings

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 operations sections of the data sheet.Exposure to  absolute   maximum  ratings  of  extended   periods  can  adversely  affect device reliability.
