A holographic lenslet array device with variable focal power is presented. It consists of two holo-lenslet array components. The i x jth pair of the holo-lenslets between two components forms a channel, which has a symmetrical off-axis configuration formed by a Leith-Upatnieks holo-lenslet and a Brandt holo-lenslet. Because of its variable focal power, it is more flexible than others. It can achieve the function of multi-signal processing, and can be used as array illuminators for the optical parallel interconnect applications.

We describe a technique to design and implement a wavelength-division-multi/demultiplexing device with a reflection substrate-mode grating pair in dichromated gelatin. This device is based on a diffraction volume grating pair, which provides and angularly dispersive function, to separate optical signals at different wavelengths through the dielectric substrate with total internal reflection. In this structure, the channel separation is enhanced by multiple reflections at substrate-air interfaces with a shorter longitudinal distance. Normally incident coupling and on-axis output imaging with this structure provide easier alignment with coupled optical fibers. The device with a polarization-insensitive high efficiency ( > 80 %) for 76-nm bandwidth has been fabricated.

A novel substrate-mode grating pair structure for polarization and leaky beam splitting is presented for application to magnetooptic heads. These light weight and compact elements provide better flexibility and easier alignment for system applications. Optimum designs for these two types of beam splitters and theoretical evaluation of the system performance are discussed in detail. Preliminary experimental results are also given to demonstrate the feasibility of application of these substrate-mode grating pairs in a magnetooptic head.

A multiband wavelength-division-demultiplexing (WDDM) structure, which incorporates cascaded substrate-mode holograms, is presented. The method can be used to design a WDDM device that consists of two or more layers of fundamental units (i.e., substrate-mode holograms). The fundamental unit is based on a diffracted grating and a substrate that include angular dispersion, wavelength bandwidth, and total internal reflection, which can be used to separate optical signals of different wavelengths. We have designed and built a multiband WDDM device, incorporating cascaded substrate-mode holograms in dichromated gelatin.

Polarization-selective substrate-mode grating pairs have been designed and fabricated. Based on these devices, we propose the structures of optical switches for two-sided network and one-sided network applications, respectively. These compact and light-weight optical switches with normally incident and output coupling provide better flexibility and easier alignment for system applications.

The optimisation of an optical receiver is discussed and transient charcteristics of two basic simple integrated receivers in CMOS systems are analysed and compared in detail. In analysis, a maximum current parameter is developed and used for optimisation design. Among these two receivers, the low-impedance configuration is presented for high-speed operation. SPICE simulation and preliminary experimental results with discrete devices are also illustrated and discussed.

General design of polarization-selective volume holograms is discussed in detail. The required diffraction angles for these highly polarization-selective elements are calculated. An effective index-modulation parameter is defined and used to calculate the required index-modulation value at any specified operating wavelength. Design examples of operating wavelengths at 780, 830, 1050, 1300, and 1550 nm are given. Highly polarization-selective substrate-mode grating pairs for 780-nm operation were fabricated to verify the idea. These elements are suitable for applications in optical switching networks and magneto-optic data storage systems.

We present theoretical and experimental studies of a novel substrate-mode grating pair structure for wavelength-division-multiplexing/demultiplexing applications. Normally incident coupling and on-axis output imaging with this device provide easier alignment with coupled optical fibers. We have designed and fabricated wavelength-division-multiplexing devices that are implemented by polarization-insensitive high-efficiency (> 85%) substrate-mode holograms. Three-channel demultiplexing experiments have also been successfully demonstrated with the limited available wavelength range of our diode-laser system.
