Passive mode locking of clockwise and counterclockwise emission directions in a ring semiconductor laser

We experimentally demonstrate passive mode locked operation in a macroscopic semi- conductor ring laser. Pulses in CW direction are accompanied by drops in CCW directions. We interpret this regime as a result of coupling and competition between clockwise and counterclockwise emission directions.
