Optical microwave generation using modified sideband injection synchronization with wide line-width lasers for broadband communications

In future generation space based phased arrays and in pico-cellular broadband mobile communication systems operating at microwave frequencies optical techniques for transport and generation of electrical signals are widely used. In general, there are two main classes of optical transmitting and generating microwave frequencies: (1) methods using direct or external intensity modulation of lasers and (2) heterodyning method using two coherent optical waves. The present paper dwells on the second method. The present paper overcomes the major practical limitations of optical sideband injection locking. Simulation results have been given in support of the analytical result.
