The effect of the height difference between the two shoulders of the Kovar bracket on the rate of change of SLD full temperature power

In superluminescent diode (SLD), the height difference between the two shoulders of the kovar bracket (referred to as the shoulder difference) has a significant impact on the rate of change of SLD full temperature power (ΔP). To reduce the rate of change of SLD full temperature power, this paper verifies the influence of four sets of double shoulder differences at different heights on SLD full temperature power, and establishes a quantitative relationship between double shoulder differences and SLD full temperature power stability. The experimental results show that the shoulder difference is less than 10um, the mean Δ P is 1.86%, and the standard deviation is 0.008; the shoulder deviation is between 10um and 20um, with a mean Δ P of 2.88% and a standard deviation of 0.014. The shoulder deviation is between 20um and 40um, with a mean Δ P of 3.87% and a standard deviation of 0.016; the shoulder difference is greater than 40um, with a mean Δ P of 5.9% and a standard deviation of 0.040.
