Abstract, In the interest of ease of manufacture hybrid lasers of, distributed-Bragg-reflector type are preferred for use as light sources in optical communications. Such lasers are made to operate away from mode instabilities by adjusting a laser parameter such as e.g. laser temperature, thereby assuring highly error-free transmission. Alternatively by suitable, design of the Bragg reflector it is possible to render mode instability of negligible influence on error rate. (FIG . 1)
