This thesis focuses on the design, fabrication, and characterization of passive silicon photonic devices specifically, we present two novel passive silicon photonic devices based on the popular 220 nm soi platform, namely an ultra- broadband and low-loss silicon adiabatic optical power splitter and an ultra- broadband and. This thesis investigates the impact of backreflections on single-fiber bidirectional wdm- pons a wdm-pon with various optical line terminals (olts) and colorless onu configurations is presented broadcasts the traffic through a passive optical power splitter at the rn to all onus in the access network and accordingly. Data transmission techniques for short-range optical fiber and wireless communication links tien-thang pham ph d thesis december 2012 abstract the research work described in this thesis is devoted to experimental inves- thermal stability issues , their cost is still higher than power splitters of. Ideally, the splitter should divide the input power equally into the output channels without significant reflection or radiation losses and should be compact in size in this thesis we have proposed different techniques of optical power splitting using (a) y-junction, (b) pc line defect waveguides integrated with multimode.
This is done by use of an optical splitter, wherein half of the carrier wave power is supplied to the detector and the other half is modulated with new signal data the new data is then transported back to the original system the aim of this thesis is to provide an overview of various carrier wave reutilization techniques, their. Ing non-uniformity of split power over all the output waveguides) decreasing waveguide core size, it is pos- sible to suppress presence of the first mode and this way to reduce non-uniformity keywords gpon, mmi splitter, multimode interference splitter, optical access networks (oan), op- tical network unit (onu ), optical. A thesis subrnitted to the faculty of graduate studies and research in partial fülfillment of the operation of the gmzi as a variable-ratio optical power splitter, which in specific instances tùnctions as an optical input switch properties ieads to new designs for non-blocking n x n optical switches that possess the benefits of.
So a typical ont turns the light pulses into ethernet signals onts are connected to the olt by means of optical fiber and no active elements are present in the link a single ont can serve as point of access for one fiber to the home customers splitter is a passive element which, in the downlink, distributes the input power.

This thesis proposes and demonstrates the principle of a novel opto-vlsi-based adaptive optical splitter/combiner for next generation dynamic optical telecommunication networks the proposed splitter structure enables an input optical power to be split adaptively into a larger number of output fibre ports, through optimized.
Main contribution of this thesis is in demonstrating that all optical multicast can be made practical for both 1:2 splitters and 1:n an optical splitter splits the input signal into multiple identical output signals since an optical splitter is a passive device the power of each output signal is 1/n times the input signal in addition to. Then using optimized bends, a two-dimensional photonic crystal power splitter based on directional coupling is analyzed effects of changing leunberger d 2004 experimental and numerical investigation of two-dimensional photonic crystals for application in integrated optics phd thesis epfl  olivier s, benisty h,.
