Manufacturing Methods and Technology Program for Low Cost Hybrid Silicon Photodetector Modules

摘要

Two silicon photodiode-amplifier modules have been developed and brought to the stage where moderate production rates have been demonstrated. The first of these in SAPDM-1 built to Specification MMT-769776-2. This unit uses a silicon avalanche photodiode, together with a hybrid preamplifier, in a TO-8 size package and is optimized to detect pulses of 1.06 micrometer radiation in a rangefinder application. The second module is SAPDM-2 built to specification MMT-769776-3. This unit uses a silicon avalanche photodiode together with a hybrid preamplifier on a special 1'' diameter package for use in fibre optic applications at 820nm. This unit also contains temperature compensation circuitry which keeps the characteristics of the unit constant as the temperature changes. (Author)
