The high security of optical phased array (OPA) signals is an important requirement for OPA-based wireless communication (OWC). We propose a method improving the OWC systems using optically injection-locked (OIL) semiconductor lasers. theoretically demonstrate amplitude and phase modulation OIL-OPA elements by controlling injection-locking parameters OIL When Taylor window function applied as p...

A novel approach to monitoring the laser injection-locking (IL) state is proposed and verified using side-mode suppression ratio (SMSR). In a photonics experiment for IL, an optical spectrum analyzer with conventional criterion of 35-dB SMSR conventionally used detect locking Fabry–Pérot (FP) multiple longitudinal modes external master one mode. Since not always sufficient condition, we propose...

This work presents an in-depth investigation of the nonlinear behavior two mutually injection-locked oscillators through inductor coupling. An analytical formulation, solved innovative procedure, facilitates understanding qualitative transformations in system solutions when increasing coupling factor. The analysis demonstrates that, a manner similar to unilaterally oscillators, families disconn...
