    摘要: An optical device comprising an optical device comprising a Mach-Zehnder interferometer having a first 2×2 optical coupler, a second 2×2 optical coupler, a first optical arm, and a second optical arm. The first and second arms connecting corresponding pairs of optical ports of the first and second 2×2 optical couplers. The second optical arm has a longer optical path than the first arm. The device also comprises one or more optical resonators optically coupled to the first optical arm and an optical splitter. The optical splitter is coupled to deliver a portion of an input optical signal to one port of the first 2×2 optical coupler and to deliver a remaining portion of the input optical signal to one port of the second optical coupler.

    摘要: An authentication loading control feature enables a service provider to control the number of authentication procedures or percentage of time that authentication procedures are performed by a network element adapted to perform authentication procedures (e.g., a Serving GPRS Support Node (SGSN) of a UMTS network); and an information recapture feature enables the network element to obtain, in the absence of authentication, UE information that conventionally would have been received as a part of the authentication procedure as needed, for example and without limitation, to support charging and lawful intercept functions.

    摘要: An apparatus comprising a planar optical structure that includes an input coupler, first and second planar waveguides and an output coupler, all on a planar substrate. The input coupler is configured to divide an incoming light into two input light beams. Each of the first and second waveguides is configured to receive one of the two input light beams. The first waveguide has a first core with a width that is greater than a width of a second core of the second waveguide. At least one of the first or second planar waveguides is birefringent. The output coupler is configured to receive the light beams after passage through the first and second waveguides. A first output light beam from the output coupler is substantially TE polarized light and a second output light beam from the output coupler is substantially TM polarized light.
