Abstract

The performance of electroabsorption transmission modulators incorporating a fibre-matched externally tunable, asymmetric Fabry-Perot cavity is investigated, The theoretical analysis includes the effects of the optical power source characteristics, cavity finesse, and the power coupling loss for single fibre devices. The results show that for a laser source, fibre with standard numerical aperture of 0.2, fibre end reflectivity of 0.8, a cavity length less than four times of the working wavelength is required to obtain 6 dB contrast with an insertion loss less than 2 dB and a modulation change larger than 50%
