چکیده
A new model is presented for a step-index fiber in the form of an equivalent slab guiding structure. This model simplifies the analysis of fiber directional couplers and coupler half-blocks with dielectric and metallic superstrates. Simple empirical formulas to obtain the model parameters are also given. The use of this model is illustrated with some numerical examples.

Analysis of Tunable Single-Mode Fiber Directional Couplers Using Simple and Accurate Relations RAM AN AND TEWARI AND K. THYAGARAJAN
We present simple and accurate relations for the study of parallel and curved tunable single-mode fiber directional couplers employing step-index or graded-index fibers. Analytical results for the various coupler parameters such as coupling coefficient, effective interaction length, tunability, and channel wavelength separation in directional coupler wavelength filters are presented. These resu...
متن کاملDevelopment of Forward-wave Directional Couplers Loaded by Periodic Shunt Shorted Stubs
In this paper a new procedure for designing forward-wave directional couplers using periodic shunt short circuited stubs is proposed. A new type of cell using these stubs, which enlarge the phase difference between even- and odd modes of a uniform microstrip coupled line is introduced. Using the equivalent circuit model for even- and odd-modes of the proposed cell, the elements of the ABCD tra...
متن کاملAn Out-of-Plane Grating Coupler for Efficient Butt-Coupling Between Compact Planar Waveguides and Single-Mode Fibers
We have designed and fabricated an out-of-plane coupler for butt-coupling from fiber to compact planar waveguides. The coupler is based on a short second-order grating or photonic crystal, etched in a waveguide with a low-index oxide cladding. The coupler is optimized using mode expansion-based simulations. Simulations using a 2-D model show that up to 74% coupling efficiency between single-mod...
متن کاملDevelopment of a vertical optical coupler using a slanted etching of InP/InGaAsP waveguide
We demonstrate a simple and efficient optical coupler for vertical coupling between optical fibers and InP-based waveguides using a slant-etched mirror. The angle of the etched mirror can be controlled by using an aluminum jig with a beveled surface inserted under the substrate during RIE (reactive ion etching) of InP/InGaAsP. The offchip coupler is fabricated simultaneously with a high-mesa wa...

Directional couplers are passive devices which are used as power dividers and combiners in microwave, millimeter and terahertz systems. By the use of substrate integrated waveguides (SIW) for the design of such devices, the advantages of waveguide and printed circuit (PC) technologies are utilized simultaneously, such as low cost, small size, low transmission and radiation losses. In this paper...
