Abstract:

A push-pull magneto-optical modulator of laser radiation with an active element of the yttrium iron garnet is proposed. The disadvantages of conventional magneto-optical and electrooptical modulators of laser radiation operating in the near infrared (NIR) wavelength range (1.1-5.5 micron) are discussed. An optical scheme of the push-pull magneto-optical modulator is proposed. It is shown that the proposed optical modulator eliminates the losses of the net power of the input signal, when receiving weak signals allows obtaining a sufficiently large signal/noise ratio in the optical channel. This fact allows use the push-pull optical modulator in the remote control of surfaces, the fiber-optic communication, the data transmission and processing of information.
