Bragg properties of efficient surface relief gratings in the resonance domain
نویسندگان
چکیده
Closed form analytical solutions of diffraction efficiency for transmission surface relief gratings in the resonance domain are presented. These are obtained by modeling the surface relief gratings with equivalent graded index gratings having Bragg properties, so as to allow for an optimum choice of grating parameters that would lead to high diffraction efficiencies. The calculated and experimental results reveal that the diffraction efficiency can be greater than 85% with optimized grating parameters within their certain strict limits. 2004 Elsevier B.V.

Effective grating theory for resonance domain surface-relief diffraction gratings.
An effective grating model, which generalizes effective-medium theory to the case of resonance domain surface-relief gratings, is presented. In addition to the zero order, it takes into account the first diffraction order, which obeys the Bragg condition. Modeling the surface-relief grating as an effective grating with two diffraction orders provides closed-form analytical relationships between...
متن کاملAnalytic design and solutions for resonance domain diffractive optical elements.
A model for designing and analyzing complicated surface relief diffractive elements in the resonance domain is developed. It is based on subdividing the complicated diffractive element into many highly efficient local diffraction gratings whose surface relief modulations can be effectively characterized as slanted volume gratings for which closed form analytic solutions exist. The model is illu...
متن کاملSurface-relief fiber Bragg gratings for sensing applications.
We present a new type of fiber Bragg grating (FBG) in which we etch the grating into the flat surface of a D-shaped optical fiber. Instead of being written in the core of the fiber, as are standard FBGs, these surface-relief FBGs are placed in the cladding above the core. These gratings are a viable alternative to standard FBGs for sensing applications. We describe the fabrication process for e...
متن کاملOptical pulse compression based on nonlinear silicon waveguides and chirped Bragg gratings
Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...
متن کاملFiber Bragg Grating Sensors and Sensor Arrays
Fiber Bragg gratings have found widespread application in sensor systems, e. g. for temperature, strain or refractive index measurements. The concept of fiber Bragg gratings allows also in a simple way the realisation of arrays of such sensors. The development of such optical fiber sensor systems often requires special fibers and grating structures which may go beyond more conventional Bragg gr...
