Abstract
Light absorption by injected holes in n‐type InSb near liquid nitrogen temperature is used to modulate the CO2 laser. A P+ N junction device is described which achieves a good modulation efficiency up to a few megahertz with a driving power of 300 mW. Such a modulator can be controlled by applying an external dc magnetic field.Keywords
