The authors report the analytical small-signal modeling of the distribution of minority carriers in the base of a transistor laser and of the high-speed dynamics of the device. The modeling is based on analytically solving the continuity equation and the rate equations, which incorporate the virtual states as a conversion mechanism. Wide-band operation of the transistor laser along with the suppression of the relaxation oscillation frequency peak is demonstrated.

    When bubbles expand and collapse close to boundaries, a shear flow is generated which is able to remove particles from the surface, thus locally cleaning it. Here the authors demonstrate experimentally with microparticle tracking velocimetry that the strongest forcing of particles occurs during...
