High amplitude fast optical modulator

A method of generating an electromagnetic signal comprising the steps of:

• a) directing incident radiation at a material, said incident radiation comprising a first parameter having an initial value;
• b) providing a plurality of stimulations to said material to change said value of said first parameter of radiation;
• and
• c) generating a pulse of radiation from said continuous radiation, said pulse of radiation comprising a second value of said first parameter, said pulse further comprising a pulse width, wherein said pulse width is shorter in time than is achievable with a single one of said plurality of stimulations or said second value is greater than can be achieved with a single one of said plurality of stimulations.

A device, comprising:

• a material for modulating radiation;
• a source of radiation configured to provide radiation to said material, said radiation having a first segment;
• an electrical pulse generator;
• and
• a plurality of electrical conductors configured to receive pulses from said electrical pulse generator, said conductors extending across different portions of said material, said conductors arranged in a circuit to provide said pulses at said material to intersect said first segment of said radiation.

A method of providing a signal comprising the steps of:

• a) forming a light pulse comprising an on-portion and an off-portion, said off-portion having a residual magnitude;
• b) directing said pulse through a saturable absorber to absorb residual off-signal;
• and
• c) amplifying said pulse after said saturable absorber step.

A method of fabricating a device, comprising the steps of:

• a) providing a substrate;
• b) forming a superconductor on said substrate;
• and
• c) forming a magneto-optical material on said superconductor.
