Laser-Written Optical-Path Redirected Waveguide Device for Optical Back-Plane Interconnects

Highly flexible polymeric optical waveguide for out-of-plane optical interconnects.

In this paper, we reported high speed optical test on polymeric optical waveguide array with embedded 45 masculine micro-mirrors on flexible substrate for out-of-plane optical interconnects. The waveguide array was bent with curvature ranging from 61 mm to 5mm. As the bending radius decreases, the average insertion loss increases from 3.4 dB to 7.7 dB for single-mode fiber (SMF) coupling and fr...

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...

Laser-written nanoporous silicon ridge waveguide for highly sensitive optical sensors.

We report that low-loss ridge waveguides are directly written on nanoporous silicon layers by using an argon-ion laser at 514 nm up to 100 mW. Optical characterization of the waveguides indicates light propagation loss lower than 0.5 dB/cm at 1550 nm after oxidation. A Mach-Zehnder interferometer sensor is experimentally demonstrated using the waveguide in its sensing branch, and analytical res...
