waveguide channels, the field pattern in the MZ output becomes asymmetric with
redistribution of the field intensity from the main maximum to the side maxima.
Now we consider the injection strip laser (Fig. 7.6). The strip contact occupies the
limited part and is equal l 1 , approximately from 5 to 20 wavelengths of the laser
emission. Mirrors are formed by the sheared facet ways of the crystal.
