Abstract: A method, an apparatus, a communication device, and a computer program product for biometric identification of users who wants to access the network, are provided. The apparatus may be an Internet Gateway Device, Router, Customer Premise Equipment, or a Managed Gateway device. The apparatus may detect biometric information using a computer software program and sensors. The apparatus may then use computer program to compare the detected biometric information of a user with stored biometric information associated with a stored user's biometric profile of a plurality of user profiles. The apparatus may then determine whether to provide the web access with full or limited privileges based on comparison of received provided biometric information with stored biometric information or even deny the access request, received from a communication device.

Abstract: A robust sensor, suitable for dipping into fluid wells, includes (a) a stem; (b) a whispering gallery mode (“WGM”) resonator mechanically supported by the stem; and (c) feed and pickup optical fibers optically coupled with the WGM resonator and mechanically coupled with the stem, thereby defining a stem-resonator-fiber assembly, wherein a portion of the stem-resonator-fiber assembly including the WGM resonator can fit within an imaginary cylinder having a diameter of 7 mm (or 2 mm, or even 1 mm). Such a whispering gallery mode (“WGM”) dip sensor, including (1) a stem, (2) a WGM resonator, and (3) feed and pickup optical fibers, may be made by (a) fabricating the WGM resonator and the stem from an optical fiber; (b) fabricating tapers on the feed and pickup fibers; (c) positioning tapers of the feed and pickup fibers relative to the WGM resonator such that an optical coupling between the tapers and the WGM resonator is established; and (d) mechanically coupling the stem with the feed and pickup fibers.

Abstract: An all-photonic method to cause a WGM resonator to self-tune to a given wavelength is described. Such all photonic approaches include simply superimposing intense light of a wavelength in a range different from that of a signal wave. The wavelength of the pass band for the signal wavelength can be tuned by adjusting the wavelength (and/or the intensity) of the intense light.
