    摘要: A MEMS comprises a back-plate (7) having an inner portion (7a) and an outer portion (7b), the inner portion (7a) connected to the outer portion (7b) by a sidewall (7c). A raised section or anchor ring (60) is formed in the outer portion (7b) of the back-plate, in a region of the back-plate near the inner perimeter of the outer portion. The anchor ring may comprise angled sidewalls. The thickness of the back-plate may be greater than the thickness of the material supporting the anchor ring. Embodiments are also disclosed in which a membrane comprises a raised portion and an outer portion connected by an angled sidewall.

    摘要: A method of fabricating a micro-electrical-mechanical system (MEMS) transducer comprises the steps of forming a membrane (5) on a substrate (3), and forming a back-volume in the substrate. The step of forming a back-volume in the substrate comprises the steps of forming a first back-volume portion (7a) and a second back-volume portion (7b), the first back-volume portion (7a) being separated from the second back-volume portion (7b) by a step in a sidewall of the back-volume. The cross-sectional area of the second back-volume portion (7b) can be made greater than the cross-sectional area of the membrane (5), thereby enabling the back-volume to be increased without being constrained by the cross-sectional area of the membrane (5). The back-volume may comprise a third back-volume portion. The third back-volume portion enables the effective diameter of the membrane to be formed more accurately.

    摘要: An arrayed waveguide grating (AWG) device comprising a substrate having a first array of waveguides optically coupled between first and second slab couplers and a second array of input-output waveguides optically coupled at first ends thereof to an input/output side of the second slab-coupler. The input/output waveguide are tapered at first end portions thereof so as to increase in width towards the second slap coupler, and the width (W) of the first ends of the input/output waveguides varies across the second array in a manner so as to increase uniformity of at least on performance parameter, for example adjacent crosstalk (AXT). In the described embodiment, the width (W) of the tapered waveguide ends increases from one side to the array of input/output waveguides to the other, so as to keep the separation(s) between the input/output waveguides.
