We experimentally demonstrate the phase relations of three-port gratings by investigating three-port coupled Fabry-Perot cavities. Two different gratings that have the same first-order diffraction efficiency but differ substantially in their second-order diffraction efficiency have been designed and manufactured. Using the gratings as couplers to Fabry-Perot cavities, we could validate the resu...

We report what may be the first documented case of an anterior mediastinal abscess due to infection by Actinobacillus actinomycetemcomitans. This small, fastidious Gram-negative coccobacillus is a normal component of the oral flora of healthy individuals,' but rarely a human pathogen. It was first described in 1912 by Klinger2 in association with actinomycosis and has since been identified as t...

Bordetella bronchiseptica is a gram-negative coccobacillus, which causes respiratory infection in dogs, rabbits, and pigs, and is rarely a human pulmonary pathogen. We present 2 immunocompromised patients diagnosed with B. bronchiseptica pneumonia. To our knowledge, these are the first reports of this disease in patients with B-cell lymphoma and an orthotopic cardiac transplant. In this report,...

Aggregatibacter aphrophilus (formerly Haemophilus aphrophilus/paraphrophilus) is a small Gram-negative coccobacillus with fastidious growth requirements. It is a normal commensal of the human oropharynx and upper respiratory tract, and it can infrequently cause invasive human diseases, including bone and joint infections and subacute infective endocarditis. Cases of liver abscess caused by Aggr...

We experimentally demonstrate the phase relations of 3-port gratings by investigating 3-port coupled Fabry-Perot cavities. Two different gratings which have the same 1st order diffraction efficiency but differ substantially in their 2nd order diffraction efficiency have been designed and manufactured. Using the gratings as couplers to Fabry-Perot cavities we could validate the results of an ear...
