Abstract
Restrictions on the frequency of a carrier signal are removed. This invention comprises a power section for receiving the carrier signal and creating an internal voltage, a clock-generating section for creating an internal clock based on a clock pulse that is carried by the carrier signal, a memory section, a writing section for storing data that is carried on an optical signal in the memory section, and an output section for reading the data in the memory and load-modulating the carrier signal.
