Integrated holographics is a novel photonics technology made possible by recent advances in semiconductor manufacturing technology and planar waveguide fabrication. The technology’s corner stone, the holographic Bragg reflector (HBR), is a slab-waveguide based, nanoscale, refractive-index structure that merges, for the first time, powerful features of holography, such as single-element spectral...

We demonstrate, for what is believed to be the first time, the design of diamondlike photonic crystals made by holographic lithography based on five-beam interference. All five beams are launched from the same half-space, and the exposure can easily be realized by a single diffractive optical element. The photonic structure can be constructed through the translation of the interference pattern ...

The holographic optical switches are three-dimensional devices, having the characteristics of flexibility and compactness. The procedure to realize a 4×4 active splitter and active combiner network with holographic optical switches is discussed in detail. After optimum design, the unique features of compactness and flexibility of holographic optical switches not only significantly saves space o...

Optical scanning holography is a real-time holographic recording technique in which holographic information about a three-dimensional 3D object is acquired using a single two-dimensional active optical scan. Applications of the technique include optical scanning microscopy, pattern recognition, 3D holographic display, and optical remote sensing. This paper introduces the basics of optical scann...

A method is developed for analytically determining the holographic optical element phase function that is optimum for transforming a set of input wave fronts into a corresponding set of output wave fronts. These sets are allowed to be infinite in the sense that the wave-front phases can be given as functions of continuous parameters. The method can be tolerant of specified wave-front aberration...

A number of methods for producing holographic optical elements (HOEs) for use in projecting integral images in holographic stereogram printers are presented, with emphasis on application to Ultragram format one-step stereograms. Creation of HOEs to replace standard diffusion screens and enhance stereogram printer imaging properties and efficiency is discussed. Monolithic and integral holographi...

A novel 16-channel optical backplane bus with volume holographic optical elements (VHOEs), operating as diffraction grating beam alignment guides, was designed and fabricated for a high-performance computing system multi-slot bus. These thin film VHOEs were fabricated to diffract light beams for each bus slot into a glass wave-guiding plate (refractive index 1.52) for total internal reflection ...

Nowadays sensors and especially biosensors play an important role in medical diagnosis and detection of food and environment contaminations. Biosensors’ facilities have been improved significantly by using technologies such as surface plasmon resonance, microfluidics, laser, and electrochemistry. These technologies are now available on chips in micro- and nano-scale and are capable of mea...
