Variational Treatment of the Diffraction at the Facet of d.h. Lasers and of Dielectric Millimeter Wave Antennas

Abstract: This paper presents an accurate variational treatment of the diffraction of TE and TM waves by an abrupt transverse discontinuity in a dielectric waveguide, such as the mirror of a double heterostructure (d.h.) injection laser, or the end plane of a dielectric slab antenna for millimeter waves, under the assumption of small aspect ratio. A matrix representation of the Green's function is derived analytically, in the limit of small efective frequency, for the TE case. For the TM case, the complication introduced by the discontinuity of the transverse electric field across the dielectric interface is discussed in detail. The numerical examples refer to the d.h. laser configuration. Both transverse directions (perpendicular as well as parallel) to the junction are studied. The effect of mode coupling at the mirror of a LOC laser as well as the effect of an antireflection coating are investigated.

Low profile electrical connector

Abstract: An electrical connector includes a dielectric housing having a terminal-receiving passage defining a terminal-insertion axis for receiving a mating terminal member. A stamped and formed sheet metal contact member has a contact end disposed in the passage and a terminal end projecting from the housing. The housing has top and bottom walls, with the terminal-receiving passage extending in a direction therebetween. A slot is provided in a side wall of the housing communicating with the passage. The contact end of the contact member is inserted into the slot and is generally planar and has a terminal-receiving slot. The plane of the contact end and the slot are disposed generally transverse to the terminal-insertion axis. The contact member includes an intermediate portion located adjacent the contact end to provide additional flexiblity to the contact arms at the contact end.

Fiber-optic rotation sensor

Abstract: A fiber-optic rotation sensor comprises a coil of polarization-holding, single-mode optical fiber (25) having a core (26) with a non-circular cross-section defining two transverse orthogonal axes, the outer surface (28) of said fiber having a non-circular cross-section with a predetermined geometric relationship to said orthogonal transverse axes, a laser source (30) coupled to one end of said fiber (25) for supplying said fiber (25) with an optical signal having a fixed polarization plane, said non-circular outer surface of said fiber (25) forming a reference surface (29) for precisely aligning one of said transverse orthogonal axes of said fiber core (26) with said fixed polarization plane of the optical signal from said laser source (30).
