We have proposed a new ultra-compact optical demultiplexer based on metal-insulator-metal plasmonic waveguides aperture-coupled to the ring resonators. Our proposed device has high performance, small footprint, and high potential for integration and development to more channels.

Abstract In this paper, we report the completion of a prototype hardware ATM (Asynchronous Transfer Mode) cell-stream splitter for a multi-media workstation. It describes some of the experiences encountered while designing and testing the splitter’s interface to the workstation’s system bus. A summary of the test procedures is given, including a report on the recent demonstration of the prototy...

Odd and even number detection is an important mathematical operation. Generally when any divisible by 2 then it called number, otherwise, odd number. Division can be easily obtained putting a point before the least significant bit of binary As example (27)10 = (11011)2 divided its result will (1101.1)2 (13.5)10. Hence we find fractional as logic-1 say that odd, even. This operation using demult...

Abstract A novel plasmonic unidirectional coupler and its extension to a multiplexer/demultiplexer are proposed simulated. The structure can be etched adjacent metal-insulator-metal (MIM) waveguides which result in considerable reduction footprint of optical signal processing systems. Simulated results show very good agreement with design. Extinction ratio (ER) more than 11 dB was achieved for ...

The performance of a chirped waveguide grating as a wavelength demultiplexer has been investigated. Considerations include TE-‘LX, TE-TM and TM-TM mode coupling for different incident angles and waveguide parameters. The spectral response of the chirped sinusoidal surface relief grating in the optical waveguide has been studied by means of Local Normal Mode Expansion (LNME) theory to account fo...

A simultaneous strain and temperature measurement method using a Fabry-Perot laser diode (FP-LD) and a dual-stage fiber Bragg grating (FBG) optical demultiplexer was applied to a distributed sensor system based on Brillouin optical time domain reflectometry (BOTDR). By using a Kalman filter, we improved the performance of the FP-LD based OTDR, and decreased the noise using the dual-stage FBG op...

this study is to measure the impact of the insertion of demultiplexers based on Bragg grating filter on DWDM transmission system. An optical link has been developed using a simulator system.The impact of demultiplexers on 10 Gbit/s DWDM system is investigated for NRZ-OOK coding formats. Performances of demultiplexers with different crosstalk, filter bandwidth and insertion losses are analyzed t...

We present an analysis of the optical loop mirror in which a nonlinear optical element is asymmetrically placed in the loop. This analysis provides a general framework for the operation of a recently invented ultrafast all-optical switch known as the terahertz optical asymmetric demultiplexer. We show that a loop with small asymmetry, such as that used in the terahertz optical asymmetric demult...

This paper proposes a novel wavelength division multiplexer (WDM) demultiplexer design for dense WDM networks. The proposed demultiplexer consists of rectangular shaped periodic frequency filters connected in series. These rectangular filters can be formed with an apodized onedimensional (1-D) photonic crystal structure on a ridged semiconductor waveguide. A design example is given for such fil...
