SCATTERING MEDIA by XIAOLONG ZHANG (Under the Direction of Peter Kner) ABSTRACT Random light scattering in inhomogeneous media causes strong wavefront aberrations and makes it impossible to focus light. Many wavefront correction techniques have been recently demonstrated to control light propagation in these media. Phase modulation with a spatial light modulator (SLM) and digital light modulato...

Compressive sensing (CS) theory has drawn great interest in recent years and has led to new image acquisition techniques in many different fields. This research investigates a CS based active underwater laser serial imaging system, which employs a Spatial Light Modulator (SLM) at the source. A multi-scale polarity flipping measurement matrix and a model-assisted image reconstruction concept are...

We developed a high-resolution microscope based on three-dimensional structured illumination generated with two spatial light modulators. This setup enables both lateral resolution improvement by a factor two and axial localization of point like objects with nanometric precision.

A novel structure of a resonator type guided-wave electrooptic intensity modulator is introduced that uses a higher-order harmonic resonant electrode of coupled microstrip lines combined with polarizationreversed structure. The light modulation cancellation caused by the light transit-time effect in the resonant electrode, which is longer than the wavelength of the standing wave, is compensated...

Phase-only spatial light modulators are now ubiquitous tools in modern optics laboratories, and are often used to generate so-called structured light. In this work we outline the use of a phase-only spatial light modulator to achieve full complex amplitude modulation of the light, i.e., in amplitude and phase. We outline the theoretical concept, and then illustrate its use with the example of t...

We demonstrated a GHz bandwidth slow light photonic crystal waveguide based PIN Mach-Zehnder modulator with V ×L as low as 0.0464 V mm, which is the lowest figure of merit reported so far. Keywords-slow light; photonic crystal; Mach-Zehnder modulator
