Abstract : A mode development, optical time delay system for electrical signals having a highly multi-mode optical fiber having a step index profile in optical alignment with an optical source which is capable of converting an incoming electrical signal into an optical signal. By incorporating within the system a number of different components to alter or control the mode angles of the incoming optical signal, the resultant optical output signal is time delayed as it propagates through the optical fiber. This optical output signal is thereafter converted into an electrical output signal which is also time delayed in direct relation to the mode angle of the optical signal propagating through the optical fiber.
