Four-wave mixing and phsae conjugated wave generation in a semiconductor diode laser

A new method was proposed for tha generation and detection of phase conjugated optical waves from a semiconductor diode laser using a smith-type interferometer. This method has an advantage to display the spatial as well as tamporal information of the generated phase conjugated optical waves. The experimental demonstration was performed by using a 1.3μm DFB diode laser, and a remarkable agreement was confirmed between experimental and theoretical results. The present method can be generally applied to all kinds of lasers for the generation of phase conjugated waves as well as for the study of their nonlinear optical properties during the laser oscillation.
