(color online) Dynamic maps of the chaotic semiconductor laser chip 1 calculated by the largest Lyapunov exponent: (a) L = 2 mm, (b) L = 3 mm, (c) L = 4 mm, (d) L = 5 mm, (e) L = 6 mm and (f) L = 4 cm. The blue represents that the largest Lyapunov exponent is far less than zero; green is near zero; red and yellow are greater than zero.
