Radioisotope powered light modulating communication devices

A light modulating communication device comprising:

• a housing comprising at least one inner chamber, and an opening;
• at least one quantum dot positioned inside the inner chamber, wherein the quantum dot comprises CdS, CdSe, CdTe, ZnS, or ZnSe;
• a high-energy emitting source positioned within the at least one inner chamber, wherein the high-energy emitting source is a radioisotope;
• the at least one inner chamber having an opening, the at least one quantum dot physically separated from the high-energy emitting source and the opening by a gap, the gap sized to prevent evanescent wave coupling losses;
• at least one reflector positioned within the at least one inner chamber;
• and
• a modulator positioned proximal to the opening of the housing, wherein the modulator is LiNbO3 or Pb1-xLax(ZryTi1-y)1-x/4O3 (PLZT).

A method comprising:

• providing at least one quantum dot;
• providing a source emitting high-energy particles;
• the source emitting high-energy particles are contained in a housing having an opening, wherein the at least one quantum dot is physically separated from the source emitting high-energy particles and the opening by a gap, the gap sized to prevent evanescent wave coupling losses;
• contacting the at least one quantum dot with high-energy particles such that light is produced from the at least one quantum dot;
• modulating the light produced from the at least one quantum dot, wherein modulated light is produced.
