Ultra-broadband High Coupling Efficiency Fiber-to-Waveguide Coupler Using Si3N4/SiO2 Waveguides On Silicon
An easy-to-fabricate but very efficient fiber-to-waveguide coupler is theoretically analyzed and experimentally demonstrated. In this design, light from a single-mode fiber can be butt-coupled into a single-mode high-index-contrast Si3N4/SiO2 waveguide with a measured coupling efficiency of 96 % at the wavelength of 1550 nm, and > 90 % in the spectral range from 1450 nm to 1650 nm. Large horizo...
متن کاملOn-chip transformation optics for multimode waveguide bends.
Current optical communication systems rely almost exclusively on multimode fibres for short- and medium-haul transmissions, and are now expanding into the long-haul arena. Ultra-high bandwidth applications are the main drive for this expansion, based on the ability to spatially multiplex data channels in multimode systems. Integrated photonics, on the other hand, although largely responsible fo...
متن کاملParallel Optics in Waveguide Displays
In order to demonstrate the Wedge as a parallel optic we have built a flat panel multi-projector autostereoscopic 3D display. The bulk otherwise inherent in such displays has been eliminated by use of a wedge-shaped light-guide. Two 280mm (11”) diagonal VGA resolution views were formed on a 406mm (16”) diagonal screen by pointing a pair of LED-illuminated picoprojectors measuring 115x50x22mm in...
متن کاملWLAN Substrate Integrated Waveguide Filter with Novel Negative Coupling Structure
A fourth-degree Substrate Integrated Waveguide (SIW) crossed coupled band pass filter for WLAN band is designed by using a new negative coupling structure. It consists of two U shape microstrip lines on top and bottom planes with via holes at the center of them. This paper investigates the phase characteristics of negative and positive coupling structures and their effects. The design, fabricat...
متن کاملGroup-index independent coupling to band engineered SOI photonic crystal waveguide with large slow-down factor.
Group-index independent coupling to a silicon-on-insulator (SOI) based band-engineered photonic crystal (PCW) waveguide is presented. A single hole size is used for designing both the PCW coupler and the band-engineered PCW to improve fabrication yield. Efficiency of several types of PCW couplers is numerically investigated. An on-chip integrated Fourier transform spectral interferometry device...
