Abstract

Serious bit-error-rate limitations arise due to laser phase fluctuations in a class of all-fibre bit-rate limiters. Polarisation-sensitive error-rate floors exceeding 10⁻⁶ have been observed in the passbands of these devices when driven by intensity-modulated GaInAsP lasers using non-return-to-zero signalling and direct detection. A similar decline in performance is anticipated in other fibre systems containing multiple paths.
