The same is known from Ge-doped and undoped single mode (SM) fibres at about 1550 and 1300 nm. During longer irradiations (/spl les/2 d) it was found that the loss of the GI fibre at 830 nm was reduced by photobleaching, leading to approximately the same loss at 830 and 1300 nm during irradiation with higher light powers (/spl ges/10 /spl mu/W). The stronger loss increase at 1550 nm of a Ge-doped SM fibre continued for more than 70 days, leading to an about 1.5 times higher loss at 1550 nm than at 1300 nm. The reason seems to be a long-lived absorption peak in the far IR.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.

The test structures were varied in critical spacing dimensions to represent a range of layout conditions in typical CMOS circuits. SPICE simulations were used to relate changes in latchup tolerance to reduced parasitic bipolar gains and increased well and substrate resistances in these CMOS circuits. It is shown that decreasing transistor gains and increasing resistances can have competing influences on latchup threshold. These competing effects can explain the observed initial reduction in latchup threshold for some proton irradiation conditions.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.

A Nd:YAG laser is used to simulate the irradiation without any permanent damage. Two specific wavelengths are selected: 1064 nm which allows a selective excitation of the laser cavity simulating transient effects of a single particle and 532 nm which interacts with the whole device. The temporal response of the diode is first observed and its shape is interpreted as a function of the physical structure of the device. Then the variation of the time of return to equilibrium after a perturbation is presented as a function of bias current. The limitations on the optical links for both analogue and digital applications are then discussed.","PeriodicalId":135784,"journal":{"name":"1999 Fifth European Conference on Radiation and Its Effects on Components and Systems.
