Abstract

Photon recycling in semiconductor ring lasers is theoretically analyzed. Dependence of threshold current, light output and modulation speed on photonrecycling is calculated using rate equations for the carrier density and photon densities of laser mode and spontaneous emission. It is shown that photon recycling improves current versus light output characteristics and does not degrade the modulation speed. Photon recycling efficiencies for circular, square and triangular ring cavities are also examined. Although a circular structure has the largest photon recycling efficiency, it is considered that a square ring cavity, which still has a high efficicency, is the best because the number of oscillation modes is less than that of a circular one.
