    The AN/SPY-1 phased array radar, part of the Aegis Combat System deployed on modern U.S. cruisers and destroyers, "is able to perform search, track and missile guidance functions simultaneously with a capability of over targets." Likewise, the Thales Herakles phased array multi-function radar used in service with France and Singapore has a track capacity of targets and is able to.   Demultiplexers using a Rowland circle grating construction seemed to be very promising because of their compactness, simplicity and significant reductions in interconnections and assembly complexity. Therefore, the integration of these demultiplexers with active elements such as detectors and amplifiers is a major step toward a fully integrated.

    Phased array ultrasonics (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive applications are to noninvasively examine the heart or to find flaws in manufactured materials such as -element (non-phased array) probes, known technically as monolithic probes, emit a beam in a fixed direction. A virtually imaged phased array (VIPA) is an angular dispersive device that, like a prism or a diffraction grating, splits light into its spectral components. It works almost independently of contrast to prisms or regular diffraction gratings, it has a much higher angular dispersion but has a smaller free spectral aspect is similar to that of an Echelle grating which.

A 4-channel phased-array wavelength division demultiplexer with nm channel spacing at /spl mu/m has been monolithically integrated with photodetectors in InP/InGaAsP.

On chip losses are 3. AWG multi/demultiplexers are key components for high channel-count wavelength division multiplexing systems because of their use in multiplexers, demultiplexers, add-drop multiplexing, and routing.

AWG multi/demultiplexers have already been realized using silica-on-silicon, ion. Wavelength Demultiplexers. In order to be a relevant integration platform for telecom applications, it is essential to include wavelength demultiplexing into the function set.

Arrayed waveguide grating (AWG) offers a powerful way to filter and de/multiplex light. The mode of operation is based on the wavelength-dependent propagation through. An optical wavelength demultiplexer is fabricated as an integral part of an integrated circuit chip.

A waveguide in a common substrate having a chirped diffraction grating receives a number of wavelengths of optically modulated data from a single mode fiber.

The wavelengths are diffracted from the plane of the lines of the grating into discrete beams angles through the substrate and impinge on. The virtually-imaged phased array (VIPA) is a side-entrance etalon with potential application as a high-resolution spectral disperser for wavelength division multiplexing.

SOI platforms are generally limited to approximately 4 μm wavelength because above the SiO 2 absorption is too large reducing drastically their performance [].To extend the upper range of SOI platforms, SOS platforms may be employed where SiO 2 is replaced with Al 2 O 3 as cladding allowing to extend the wavelength range up to 6 μm [7, 16].Another effective method consists of replacing SiO 2.

The virtually imaged phased array (VIPA) is a new optical technique that produces a large angular novel method was developed by Dr. Masataka Shirasaki at Fujitsu Labs, Japan, in [1]. The angular dispersion of a VIPA is about times larger than those of common dif.

GaInAsP/InP long-wavelength (– μm) lasers have been widely used in long-distance optical fiber communications and monolithic integration of these lasers with other functional devices such as electroabsorption modulators and/or monitoring photodiodes (PDs), multiple wavelength laser arrays, and wavelength tunable lasers integrated with.

This paper reviews the recent progress of hybrid silicon evanescent devices. The hybrid silicon evanescent device structure consists of III-V epitaxial layers transferred to silicon waveguides through a low-temperature wafer bonding process to achieve optical gain, absorption, and modulation efficiently on a silicon photonics platform.

The low-temperature wafer bonding process enables fusion. The dielectric waveguide plays a key role to nanophotonic devices; for example, a lot of polarization routers [13][14][15] and wavelength routers or demultiplexers [9, 16, 17] are designed based.

Phased array optics is a technology that will produce three dimensional views of objects and scenery using only two dimensional displays. Display systems based on this technology-- optical phased arrays --will behave quite literally as windows onto whatever scenery we can imagine.

• AWGs are suitable for integration with photodetectors. Si0 2 AWGs for channels (wavelengths) with GHz channel spacing have been reported, as well as InP AWGs for 64 channels with GHz channel spacing.

AWG devices belong to the category of phased-array gratings (PHASARS) and waveguide grating routers (WGRs). MACH-ZEHNDER. David Large, James Farmer, in Broadband Cable Access Networks, Summary. Wavelength division multiplexing has become standard in the engineering of cable television and similar networks because it facilitates the delivery of switched services to small groups of customers.

It does this by allowing the transport of many independent signals over shared fibers and through shared optical. Optical multiplexing is the art of combining multiple optical signals into one to make full use of the immense bandwidth potential of an optical channel.

It can perform additional roles like providing redundancy, supporting advanced topologies, reducing hardware and cost, etc.

The idea is to divide the huge bandwidth of optical fiber into individual channels of lower bandwidth, so that.Phased Array Optics is the use of Spatial Light Modulators built to nanometer specifications for general manipulation of light.

The most compelling application of Phased Array Optics (PAO) is the production of three dimensional scenery that is indistinguishable from real life. The display application has been compared to a Star Trek Holodeck.
