Abstract

This paper reports an experimental study of coherent coupling of lasers using a BaTiO₃ photorefractive ring oscillator with a multiplexing holographic grating plate for fan-in/fan-out purposes. Phase locking between or among lasers was observed. However, the slow response speed (with about 10 milliwatts optical power at 632.8 nm) of the photorefractive process and the high sensitivity of the BaTiO₃ ring oscillator resulted in transverse mode instability and oscillation power fluctuation, which limits the phase locking phenomenon in this system on a temporary basis only.
