Abstract

A method is presented for compensating cavity thickness variations in conventional Fabry-Perot devices through the replacement of the input mirror with a holographic mirror, resulting in a self-tuned Fabry-Perot (STFP) device. The technique is suitable for integrating large arrays of electro-optic Fabry-Perot modulators with silicon circuitry. Experimental results of a STFP modulator are presented showing cavity thickness compensation of an electrooptic 9/65/35 bulk lead lanthanum zirconate titanate crystal having thickness variations corresponding to ∼6 Fabry-Perot fringes in a 2.5×2.5 mm2 area. The compensated modulator used an in situ recorded Fe-doped LiNbO3 holographic mirror, and had a uniform backreflection over a 2.5×2.5 mm2 area.
