ABSTRACT:
A device capable of obtaining an electromagnetic wave having an arbitrary waveform and an arbitrary frequency, generating an electromagnetic wave with an ultrahigh frequency, generating an electromagnetic wave with a variable frequency, and performing ultrafast optical control and optical modulation is provided. The quantum synthesizer of the present invention has a quantum synthesis portion comprising a number, n (n=an integer of 3 or more), of quantum wells provided in proximity to each other so as to be coupled together quantum-mechanically, each of the n number of quantum wells having the n number or number larger than n of coupled levels as a result of coupling, and is adapted to excite and synthesize the electron waves or polarizations of the respective levels, while controlling their phases and amplitudes, by means of coded light with phases and amplitudes controlled for predetermined frequencies (energies).
