Abstract

A new method is suggested consisting in timing of a laser by a small (with its amplitude within 0.02–0.18 of the threshold current) harmonic signal. The method is intended for fiber-optical systems of information transmission and processing and permits to diminish fluctuations (limiting the operation speed) of amplitude and time position of information pulses generated by an injection laser. Optimal values are found for the dc bias, coefficient of phase delay between the information signal and the timing signal, and for the timing signal amplitude.
