1. Nematic Liquid Crystal Spatial Light Modulators for Laser Beam Steering
Abstract : Laser beam control is important in many applications. Phase modulating spatial light modulators (SLMs) can be used to electronically alter the phase distribution of an optical wave-front and thus change the direction and shape of a laser beam. READ MORE

2. Multi-Level Lossless Phase Modulation in Liquid Crystals for High-Speed Spatial Light Modulators
Abstract : The spatial light modulator (SLM) is a compact device that enables highly precise control of light propagation with low drive voltages and no moving parts. By imposing a certain phase modulation onto the incident lightwave, functions such as multi-beam steering, beam shaping, and air turbulence corrections can be achieved in realtime. READ MORE

3. Surface-normal multiple quantum well electroabsorption modulators : for optical signal processing and asymmetric free-space communication
Abstract : Electroabsorption is the physical phenomenon by which the absorption of light in a medium can be controlled by applying an electric field. The Quantum–Confined Stark Effect, which makes the absorption band–edge in quantum wells very field–dependent, together with the strong absorption peak provided by excitons, are the physical foundations for the success of electroabsorption modulators based on quantum well structures in telecommunication networks.
