Strong beam coupling in mesogenic materials with photorefractive Bragg gratings

Not Accessible

Your library or personal account may give you access

Abstract

Strong beam coupling was observed in mesogenic materials consisting of low- and high-molar-mass liquid-crystal mixtures with high concentration ratios of the latter type of liquid crystal. The beam-coupling effects originate in orientational photorefractive Bragg gratings, and a weak signal beam with an intensity of 1 mW is amplified to 8 mW by energy exchange with a strong pump beam after the passage of a 50-μm-thick film under a low operating voltage of 1–4 V/μm. There is a superior net two-beam coupling gain of more than 600 cm−1 with the low operating voltage and high resolution.
