Abstract
This invention relates to an electromagnetic field receiver controller including a first and second optical transmitter, a transmission medium and an optical receiver. The first optical transmitter is configured to transmit a probe signal to the optical receiver via the transmission medium at a probe frequency and the second transmitter is configured to transmit a coupling signal via the transmission medium at a coupling frequency, wherein the probe frequency is set to excite electrons of the transmission medium from a ground state to a first excited state and the coupling frequency is set to excite electrons of the transmission medium to a predetermined excited state so as to induce an Electromagnetic Induced Transparency (EIT) effect in the electromagnetic field receiver such that an incident electromagnetic field at the transmission medium causes a detectable change in power of the probe signal at the optical receiver.
