Wavelength response of waveguide volume grating couplers for optical interconnects.
The wavelength response of a waveguide volume grating coupler (WVGC) is analyzed for coupling light from a slab waveguide into the superstrate. A leaky-mode approach is used in conjunction with rigorous coupled-wave analysis. A quantitative theoretical study of the effect of index modulation, waveguide index, and grating thickness on the wavelength bandpass of a WVGC is also presented. The FWHM...
متن کاملHigh-efficiency Silicon-On-Insulator Fiber-to-Chip Grating Couplers Using a Silicon Overlay
We present the realization of a new generation of Silicon-On-Insulator fiber-tochip grating couplers which use a silicon overlay to enhance the directionality and thereby the coupling efficiency. Devices fabricated in a CMOS pilot line show a coupling efficiency of -1.6dB and a 3dB bandwidth of 80nm.
متن کاملFiber Parametric Amplifiers for Wavelength Band Conversion
By using a loop configuration formed by a polarization beam splitter, we experimentally demonstrate that the existing wavelength-division multiplexing (WDM) sources in -band can be wavelength converted to the -band with low polarization sensitivity and low crosstalk. Using a fiber parametric amplifier as a band converter, we achieve experimentally 0.65-dB polarization sensitivity and 4.7-dB con...
متن کاملEfficient 5.2 µm wavelength fiber-to-chip grating couplers for the Ge-on-Si and Ge-on-SOI mid-infrared waveguide platform.
We present the design, fabrication and characterization of efficient fiber-to-chip grating couplers on a Germanium-on-Silicon (Ge-on-Si) and Germanium-on-silicon-on-insulator (Ge-on-SOI) platform in the 5 µm wavelength range. The best grating couplers on Ge-on-Si and Ge-on-SOI have simulated coupling efficiencies of -4 dB (40%) with a 3 dB bandwidth of 180 nm and -1.5 dB (70%) with a 3 dB bandw...
