摘要： A polarization-interferometry based tunable periodic filter includes polarization defining components such as polarizing beam splitters or polarizing beam displacers located on the input and output sides of a phase retarder such as a birefringent crystal. A polarization independent input consisting of multiple optical channels having a periodic frequency spacing is converted to a branched output of optical channels in which each branch has a periodic frequency spacing that is different from that of the input, and which are interleaved with each other. The output period is tunable by adjusting the phase delay of orthogonal polarization components. A contrast ratio of ≧20 dB can be realized. The device allows the mux/demux of up to 200 WDM channels with a 50 GHz frequency spacing. Applications of the device include a band splitter, a wavelength selective cross-connect, and a wavelength monitor.

摘要： An intelligent assisted transmission method is provided. In the method, a Multicast and Broadcast Service (MCBCS) Server transmits Multicast Broadcast Service (MBS) data to a base station in an MBS area. The base station transmits the MBS data to a user equipment. If the user equipment cannot correctly receive the MBS data, it returns a Not Acknowledgement (NACK) message to the base station. The base station transmits an intelligent assisted transmission prompt to the MCBCS Server. The MCBCS Server transmits an intelligent assisted transmission request to adjacent base stations of the base station. When the intelligent assisted transmission request is received, the adjacent base stations return an intelligent assisted transmission response. The MCBCS Server transmits the MBS data to the adjacent base stations, and the adjacent base stations transmit the MBS data to the user equipment.

摘要： An optical interrogation system is described herein that can interrogate a label-independent-detection (LID) biosensor and monitor a biological event on top of the biosensor without suffering from problematical parasitic reflections and/or problematical pixelation effects. In one embodiment, the optical interrogation system is capable of interrogating a biosensor and using an oversampling/smoothing algorithm to reduce oscillations in the estimated location of an optical resonance caused by the problematical pixelation effect which makes it easier to determine whether or not a biological event occurred on the biosensor.

摘要： A tunable light source for interrogating at least one resonant waveguide grating (RWG) biosensor having a resonance linewidth. The tunable light source includes a broadband light source that emits a light beam having a first spectral bandwidth greater than the RWG biosensor resonance linewidth. The broadband light source may be substantially spatially incoherent. A tunable optical filter having a tunable spectral linewidth is arranged to receive and filter the light beam to cause the light beam to have a second spectral bandwidth substantially the same as the RWG biosensor resonance linewidth. Label-independent optical readers that employ the tunable light source are also disclosed.
