The main advantage of using soliton pulses in optical communication systems is that the shape of the pulse remains almost unaltered over a long distance. We propose a simple method to achieve the proper power shape function of a pulse for generation of an optical soliton by using an electro-optic modulator in amplitude modulation mode. In this connection some important new characteristics of the pulse are pointed out.
Optical soliton propagation through an optical fiber is a well-established phenomenon in digital optical communication. This propagation can be exploited to secure many advantages in communication because of the unattenuated, unchirped, and undistorted Gaussian optical pulse propagated through the fiber. Here we propose a completely new scheme for controlling the power shape function of a Gaussian optical pulse propagated through an optical fiber in the form of soliton, leading to some new characteristics in connection with such propagation. To exploit this possibility an electro-optic modulator is used on the pulse before its introduction into the fiber.
