    Abstract: The invention provides an optical amplifying system having a structure with two amplification levels to amplify received optical signals. The optical amplifying system includes a Michelson interferometer, a preamplifier, and a post amplifier. In the preamplifier and the post-amplifier, respectively have a light pumping source, a wavelength multiplexer, and an optical gain media. The Michelson interferometer includes an optical coupler and an optical grating set composed of a pair of optical gratings. The optical gratings are located different optical passes, and its central wavelength is equal to the intended wavelength. The optical grating can be formed on a piezoelectric substrate or an electrothermal substrate so that the central wavelength can be changed by applying stress or heat. The intended wavelength reflected by the Michelson interferometer can therefore be adjusted. The preamplifier and the post-amplifier are coupled together through the optical coupler of the Michelson interferometer. Furthermore, an isolator can also be coupled between the preamplifier and the Michelson interferometer so as to avoid the backward propagation noise.

    Abstract: A plummet level for checking the horizontal state of a surface and locating two vertically spaced points generally required by wood working in most interior decorative works. The plummet level includes a rectangular main body divided into front and rear compartments for balance beam and weight-loaded swing link, respectively, to mount therein on a central pivot shaft. Two long clear windows are separately provided on walls of the main body facing the balance beam and the swing link. A plurality of spaced and parallel check lines horizontally extend a full length of the windows. A user may visually overlap one of the check lines on the windows and a reference level/vertical line on the balance beam/swing link to check a working surface for its horizontal or vertical state. Two extensible links are connected to two ends of the main body with four right-angled corners defined by an end plate of each extensible link always in alignment with four side walls of the main body, so that the plummet level may be easily extended to conveniently locate and mark a horizontally or vertically corresponding point at a distance longer than the main body of the plummet level.

    Abstract: Disclosed herein are toggle-mode magnetoresistive random access memory (MRAM) devices having small-angle toggle write lines, and related methods of toggle-mode switching MRAM devices. Also disclosed are layouts for MRAM devices constructed according to the disclosed principles. Generally speaking, the disclosed principles provide for non-orthogonally aligned toggle-mode write lines used to switch toggle-mode MRAM devices that employ a bias field to decrease the threshold needed to switch the magnetic state of each device. While the conventional toggle-mode write lines provide for the desired orthogonal orientation of the applied magnetic fields to optimize device switching, the use of a bias field affects this orthogonal orientation. By non-orthogonally aligning the two write lines as disclosed herein, the detrimental affect of the bias field may be compensated for such that the net fields applied to the device for both lines are again substantially orthogonal, as is desired.
