A novel flattened ring resonator design utilizing Etched Beam Splitters (EBS) in InGaAsP/InP is proposed and demonstrated. A multiple-thickness hard mask that compensates for RIE-lag realizes waveguides and EBS gaps in a single etch step. ©2009 Optical Society of America OCIS codes: 230.5750 Resonators, 250.5300 Photonic integrated circuits

Reactive ion etching (RIE) using fluorocarbon chemistry is widely used to open contact holes in dielectric layers for very large scale integration (VLSI) since it provides high anisotropy and selectivity over Si. However, it is known that the RIE leaves fluorocarbon residues on the exposed surface after etching of silicon dioxide [1,2]. These residue layers were reported to be nonvolatile, chem...
Iodine-mediated, oxidative desulfurization promoted cyclization of N-2 pyridylmethyl thioamides serves as an efficient and versatile method for the preparation of 2-azaindolizines (imidazo[1,5-a]pyridines) and rare 2-azaindolizine sulfur-bridged dimers. The 2-azaindolizines prepared in this manner are readily converted to a variety of fluorescent compounds by using transition-metal-catalyzed cr...
By means of a variational approach we find new series representations both for well known mathematical constants, such as π and the Catalan constant, and for mathematical functions, such as the Rie-mann zeta function. The series that we have found are all exponentially convergent and provide quite useful analytical approximations. With limited effort our method can be applied to obtain similar ...

In this paper, the first silicon load cell is presented designed for measuring a load up to 1000 kg. A prototype has been realised. An improved cryogenic RIE process with high aspect ratio was developed for the fabrication of thin springs. Low temperature silicon direct bonding was used for the final assembly. The mechanical structure was tested using poly silicon strain gauges. Encapsulated re...
