Patent number: 6625371Abstract: A planar waveguiding device includes at least on section of core which is located between and adjacent to two grooves. The refractive index within the grooves is substantially equal to one and the grooves are located so that the evanescent fields of optical signals travelling in the core extend into the grooves. Preferably the grooves have a direct interface with the core and they extend through a layer located above the core into a layer located below the core. Where the cores have bends, e.g. bends with radii of curvature below 2 mm the grooves are located both inside and outside the bends.Type: GrantFiled: October 23, 2001Date of Patent: September 23, 2003Assignee: British Telecommunications public limited companyInventors: David C Rogers, Graeme D Maxwell, Alistair J Poustie

Patent number: 6571037Abstract: An arrayed waveguide grating [WDG] comprises I/O slabs (53a, 53b) interconnected by a grating region (51). The grating region (51) comprises many, e.g. at least 25 and preferably 50 to 500, individual cores (61,62,63), which have different lengths so as to provide wavelength selectivity by causing phase changes in light conveyed between the I/O slabs (53a, 53b). There are bends (64) for providing the different lengths and, to improve optical guidance round the bends, empty (R.I.=1) grooves (71) are located adjacent to the inside (71.1) and outside radii (71.2) so that the evanescent fields extend into the grooves (71). In order to keep the dimensions small, which improves the optical accuracy, tight bends (preferred radii of curvature of less than 2 mm and especially less than 500 &mgr;m) are desirable. The grooves conveniently have tapered ends and they extend into straight portions adjacent to the bends.Type: GrantFiled: October 23, 2001Date of Patent: May 27, 2003Assignee: British Telecommunications public limited companyInventors: David C Rogers, Graeme D Maxwell, Alistair James

Patent number: 5734994Abstract: A safety helmet has a hard outer shell having front and rear edges. A bowl-shaped liner with front and rear edges and a peak between the edges is contoured to fit snugly in the shell so that the front and rear edges of the liner are adjacent to the front and rear edges of the shell. The liner has an interior surface contoured generally to fit a wearer's head and a corrugated exterior surface, the tips of the liner corrugations contacting the shell along multiple lines of contact. The corrugations in at least a central zone of the liner adjacent to the peak extend fore and aft between the front and rear edges of the liner such that the corrugations define valleys that are spaced from the shell to provide air passages in the helmet extending from the front of the helmet to an array of through-holes in the liner and to a vent opening in the shell adjacent to the rear edge of the liner. A valve is provided to control air flow through the passages and the through-holes.Type: GrantFiled: February 6, 1997Date of Patent: April 7, 1998Assignees: M.P.H.
