We report a novel lateral packaging approach using laser welding technique with angle polished fiber coupling to grating coupler embedded silicon photonic circuit. Measurements show the relax alignment tolerance for fiber packaging process. The packaging excess loss of 1.2 dB is achieved. The use of angle polished fiber for lateral fiber coupling enables an alternative way for cost-effective de...

Almost all direct wafer bonding has been conducted between chemical-mechanically polished substrates or between thin films that were present on top of the polished substrates. Introducing chemical mechanical polishing in the wafer bonding will make a large range of materials suitable for direct wafer bonding, which has found and will find more, applications in integrated circuits, integrated op...

The requirements of a highly tilted sample and a well-polished surface for optimal EBSD pattern collection can make traditional SEM imaging challenging. With a tilted sample, SEM SE and BSE detectors are often in non-optimal positions for electron detection. For many materials, the polished surfaces produce weak contrast with SE imaging. Traditionally placed BSE detectors must be used with care...

Rice is an important energy source for people worldwide. The rice grain consists of an endosperm, a bran layer and a germ. However, polished rice lacks the bran and germ, which are abundant in dietary fiber, vitamins and minerals. Polished rice is one of the main staples in Asian countries. On the other hand, pre-germinated brown rice (PGBR) is rapidly becoming popular as a health food in Japan...

When proximal bone stock is compromised at revision hip arthroplasty, distal fixation is often relied upon for stability of the femoral component. In such circumstances, torsional forces can result in debonding and loosening. This study compared the torsional behaviour of a cemented, polished and featureless (plain) stem with cemented, polished stems featuring fins or flutes. The finned stem co...

Basic asymmetric behavior is experimentally observed in a polished polarization-maintaining fiber coupler. As the two half-couplers are made to slide on top of each other, the output extinction ratio exhibits relatively large variations whose forms depend on the fiber that is selected for the input. We propose that a local distortion of the fiber birefringent axes, which could be caused by the ...

We report an in-line, fiber optic, broadband variable optical attenuator employing a side-polished, single-mode optical fiber integrated on a digital microfluidics platform. The system is designed to electrically translate a liquid droplet along the polished surface of an optical fiber using electrowetting forces. This fiber optic device has the advantage of no moving mechanical parts and lends...

The cytotoxicity of a series of dental casting alloys in the as-cast and polished condition was determined with cell culture techniques involving phase contrast microscopy to examine cell morphology and the succinic dehydrogenase histochemical reaction to measure any ring of inhibition of Balb/c 3T3 cellular respiration around alloys. Crown and bridge casting alloys and a nickel- and a cobalt-b...
