Laser diodes fail to focus light after high temperature
This failure mode is usually caused by using too much die attachment material during assembly, and excessively high temperatures and pulse energy levels will accelerate the failure process. Laser Diodes may fail in two ways, gradual degradation or catastrophic failure. The effect of temperature o the performance of uncooled semiconductor LD was experimentally studied. Even within the absolute maximum ratings, the life becomes shorter by using at high temperatures. For this reason, the design should include sufficient margin. A computational model for the evaluation of the thermomechanical effects that give rise to the catastrophic optical damage (COD) of laser diodes has been devised. Degradation is observed and recorded throughout the test by precise measurement of changes in the laser's operating characteristics. The latest “praeternatural” interpretation: loss of confinement (!) Back to earth: one of the most difficult Failure Analyses A layer of defects MUST.

How is silicon photonics integration technology
In a typical optical link, data is first transferred from the electrical to the optical domain using an or a directly modulated laser. An electro-optic modulator can vary the intensity and/or the phase of the optical carrier. In silicon photonics, a common technique to achieve modulation is to vary the density of free charge carriers. Variations of electron and hole densities change the real and the imaginary part of the refractive index of silicon as described by the empirical equations of Soref and B.
