Cr. Mirasso et al., PSEUDORANDOM WORD MODULATION OF SINGLE-MODE SEMICONDUCTOR-LASERS AT GHZ RATES, IEE proceedings. Part J, Optoelectronics, 140(1), 1993, pp. 26-29
The rate equations of a modulated single-mode semiconductor laser are
solved numerically to determine the region in the bias current against
frequency plane where pattern effects are important. Pattern effects
are avoided by biasing just below threshold, but they are important fo
r high-frequency modulation and bias current above threshold.
