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.

What materials are used in fiber optic sensing devices
It is well-known the propagation of light in optical fiber is confined in the core of the fiber based on the total internal reflection (TIR) principle and near-zero propagation loss within the cladding, which is very important for the optical communication but limits its sensing applications due to the non-interaction of light with surroundings. Therefore, it is essential to exploit novel fiber-optic structures to disturb the light propagation, thereby enabling the interaction of the light with surroundings and constructing fiber-opti.
