We present the development of a monolithically integratable optical isolator. The device is a semiconductor optical amplifier with magnetized ferromagnetic metal contact. 12.7dB isolation and optical transparency are demonstrated. The spectral dependence is studied. ©2005 Optical Society of America OCIS codes: (230.3240) Isolators; (250.5980) Semiconductor optical amplifiers; (230.3810) Magneto...

Sr(Ti0.6Fe0.4)O3 (STF) and Sr(Ti0.7Co0.3)O3 (STC) room-temperature ferromagnetic oxides were grown epitaxially on LaAlO3(001), (LaSr)(AlTa)O3 (001) and Si (001) substrates. Both materials were demonstrated to be magneto-optically active, and more optically transparent at 1550nm wavelength compared with other non-garnet ferromagnetic materials. As2S3/STF and As2S3/STC strip-loaded waveguides wer...

Oxide-free bonding of III-V-based materials for integrated optics is demonstrated on both planar Silicon (Si) surfaces and nanostructured ones, using Silicon on Isolator (SOI) or Si substrates. The hybrid interface is characterized electrically and mechanically. A hybrid InP-on-SOI waveguide, including a bi-periodic nano structuration of the silicon guiding layer is demonstrated to provide wave...

The Isolator 1.5 microbial tube (E. I. du Pont de Nemours & Co., Inc., Wilmington , Del.) was compared with the BACTEC radiometric detection system (Johnston Laboratories, Inc., Cockeysville, Md.) for the detection of bacteremia in children. The Isolator 1.5 is a blood culture system designed for small volumes of blood (0.5 to 1.5 ml). The method involves lysis of the cells of the patient and t...
