The challenge of engineering Fabry-P\'erot cavities that simultaneously present large tunability, high mechanical stability, and operate at cryogenic temperatures under closed-cycle conditions is solved by a combination vibration reduction techniques

OBJECTIVES In this study, we aimed to evaluate the anatomical and functional results of open cavity tympanomastoidectomy due to chronic otitis media with cholesteatoma. PATIENTS AND METHODS Between January 2003 and October 2009, 166 patients who underwent open cavity tympanomastoidectomy due to chronic otitis media with cholesteatoma in our clinic were retrospectively analyzed. Seventy-two ea...

The computation of optical modes inside axisymmetric cavity resonators with a general spatial permittivity profile is a formidable computational task. In order to avoid spurious modes the vector Helmholtz equations are discretised by a mixed finite element approach. We formulate the method for first and second order Nédélec edge and Lagrange nodal elements. We discuss how to accurately compute ...
