  Rewinding the arrow of time via phase conjugation is an intriguing phenomena
made possible by the wave property of light. To exploit this phenomenon,
diverse research fields have pursed the realization of an ideal phase
conjugation mirror, but an optical system that requires a single-input and a
single-output beam, like natural conventional mirrors has never been
demonstrated. Here, we demonstrate the realization of a one-wave optical phase
conjugation mirror using a spatial light modulator. An adaptable single-mode
filter is created, and a phase-conjugate beam is then prepared by reverse
propagation through this filter. Our method is simple, alignment free, and fast
while allowing high power throughput in the time reversed wave, which have not
been simultaneously demonstrated before. Using our method, we demonstrate high
throughput full-field light delivery through highly scattering biological
tissue and multimode fibers, even for quantum dot fluorescence.
