We discuss a real-time coherence gated three-dimensional (3-D) imaging system, based on photorefractive holography with ultrashort pulses, which has been applied to imaging through turbid media with a view to developing biomedical instrumentation. Su

We demonstrate the performance of all‐semiconductor photorefractive p‐i‐n diodes operating in the longitudinal quantum‐confined Stark geometry. Low‐temperature‐grown shallow quantum wells provide high‐mobility vertical transport, and po

Photorefractive asymmetric Fabry–Perot quantum‐well structures yield significantly enhanced diffraction during four‐wave mixing by employing the sensitive amplitude and phase control of multiple‐beam interference within the device. We present

Summary form only given. We present holographic diffraction from a broad-area thin-film holographic laser. The holographic laser is similar to a vertical-cavity surface-emitting laser (VCSEL) and consists of a 1 /spl mu/m thick GaAs active layer sand

A multiple‐quantum‐well film bonded to glass has high transmittance while performing simultaneously as a reflection asymmetric Fabry–Perot electro‐optic modulator. When the multiple‐quantum‐well structure is made semi‐insulating through

A diffractive short-cavity quantum-well Fabry-Perot is a planar photorefractive quantum-well thin film that uses multiple internal reflections to produce the largest diffraction efficiencies possible from photorefractive quantum well structures. In c
