A silicon p-n junction that is biased in avalanche breakdown mode emits visible light. Although the efficiency of such silicon emitters is poor, their ability to modulate at GHz frequencies make them a good choice for many applications including optical interconnect and optical contactless logic testing. Results demonstrate the feasibility of an all silicon optical interconnect system and an all silicon contactless testing methodology using the silicon light emitter and standard silicon detectors. The development of truly efficient silicon light emitting would enable many new applications.

This paper presents the design of a novel controller for a reconfigurable filter for the front end of an optical blood Oxygen sensor. The reconfigurability of the filter is dependant on the magnitude of the diode's current and is implemented with a feed forward loop from the ADC output. A relation between the output of the diode and the noise in the signal is proven in this paper. The reconfigurable filter enables a considerable amount of saving in power consumption and processing units and is a step towards implementing a portable and efficient blood gas analyzer for a point of care solution.
