OPTICAL COMMUNICATIONS MODULATOR DEVICE Abstract Electromagnetic radiation is modulated in response to an electrical signal which produces a variable electric field in a semiconductor .delta.-dopedstructure. A resulting device has a desirably broad wavelength range in which light intensity can be modulated, large contrast ratio between transparent and opaque states, small operating voltage, and high-speed capability as desirable in optical communications applications.
