    摘要: An add-filter device includes a plurality of ring resonators that are arranged to receive an optical signal of a specific wavelength and channel to be added onto a bus line that is arranged to receive a plurality of signals. At least one Mach-Zehnder Interferometer (MZI) structures embedded in the plurality of ring resonators. The at least one MZI structure and ring resonators provide the necessary modulation and filtering so that the optical signal can be added to the bus line without affecting the channels contained in the bus line.

    摘要: An optical device includes a first and a second splitting device. Each of the first and second splitting devices have respective first and second input ports, respective first and second output ports, and a respective transfer matrix. A first optical waveguide is optically coupled to the first output port of the first splitting device and the first input port of the second splitting device. A second optical waveguide is optically coupled to the second output port of the first splitting device and the second input port of the second splitting device. The first and second optical waveguides are configured to introduce a phase shift of π radians to the optical radiation propagating through the first optical waveguide with respect to the optical radiation propagating through the second optical waveguide. The transfer matrix of the second splitting device is the diagonal transpose of the transfer matrix of the first splitting device and the transfer matrix of the second splitting device is substantially different from the transfer matrix of the first splitting device.

    摘要: An AWG device includes a plurality of arrayed waveguides positioned close to each other. An input signal excites one of these coupled waveguides and the power is then transferred to all of the arrayed waveguides so there are enough degrees of freedom in the device to achieve any desired distribution.

    摘要: A PMD device includes a first stage that receives a signal and performs rotation about {1,0,0} on the signal. The first stage outputs a first signal. A second stage receives the first signal and performs a rotation about {0,0,1 } on the first signal. The second stage outputs a second signal that represents the alignment the PMD of various frequencies into a common direction. A third stage receives the second signal and provides the necessary frequency dependent variable in the {1,0,0} direction to cancel the PMD in any specified frequency range.
