Phase conjugate wave generation based on self-pumped four-wave mixing in a broad-area laser diode

The purpose this study is to construct the fast-response PCM only made of semiconductor gain material in a self-pumped manner, and to demonstrate the self-oscillation of the PCM cavity which may offer the drastically narrow spectral linewidth, as theoretically proposed by Petersen et al. This paper first demonstrates the destructive interference due to the phase conjugate feature in the self-pumped, angled feedback experiment using a broad-area laser diode (BA-LD).
