Using the Gaussian approximation, a method is found for determining the peak optical power required to allow laser communication at a specified bit error rate and communication data rate for the bipolar raised cosine pulses modulation format. The method is particularly applicable to laser diode communication systems, since the problem is solved subject to a constraint on the extinction ratio, which is the ratio of the peak optical power (Pmax) to the minimum (usually the lasing threshold) optical power (Pmin) available from a given laser diode. The receiver threshold may be chosen as an equal distance between Pmax and Pmin, or by implementing either an equal probability of error or minimum probability of error receiver.
