Apparatus comprising a plurality of interferometers and method of configuring such apparatus

A method comprising:

• configuring a plurality of interferometers to receive electromagnetic input signals and receive a plurality of sensor output signals from a plurality of sensors to enable the plurality of sensor output signals to be provided to the plurality of interferometers to control interference of the electromagnetic input signals by the plurality of interferometers, wherein different sensors within the plurality of sensors are configured to sense different types of characteristics such that the plurality of sensor output signals provide an indication of a plurality of different types of sensed characteristics, wherein the plurality of interferometers is provided on a single chip, and
• configuring the plurality of interferometers to provide a first output signal when the plurality of different types of characteristics sensed by the plurality of sensors correspond to a first context and a second output signal when the plurality of different types of characteristics sensed by the plurality of sensors correspond to a second context.

A computer program product comprising a non-transitory computer-readable storage medium bearing computer program instructions that, when executed by at least one processor, enable:

• configuring a plurality of interferometers that are arranged to receive electromagnetic input signals and to receive a plurality of sensor output signals from a plurality of sensors to enable the plurality of sensor output signals to be provided to the plurality of interferometers to control interference of the electromagnetic input signals by the plurality of interferometers, wherein different sensors within the plurality of sensors are configured to sense different types of characteristics such that the plurality of sensor output signals provide an indication of a plurality of different types of sensed characteristics, wherein the plurality of interferometers is provided on a single chip;
• and
• configuring the plurality of interferometers to provide a first output signal when the plurality of different types of characteristics sensed by the plurality of sensors correspond to a first context and a second output signal when the plurality of different types of characteristics sensed by the plurality of sensors correspond to a second context.
