Title: Tunable resonant grating filters
Inventor: PIETRA GIULIA
IPC: G02B6/12
Filed: 2003-12-24
Abstract: The invention relates to a tunable resonant grating filter that can reflect optical radiation at a resonant wavelength, said resonant wavelength being selectively variable. The filter comprises a diffraction grating (3), a planar waveguide (4) and a light transmissive material having a selectively variable refractive index to permit tuning of the filter, said light transmissive material forming a tunable cladding layer (5) for the waveguide, preferably a liquid crystal (LC) material. The diffraction grating (3) is placed on the opposite side of the tunable layer (5) with respect to the planar waveguide (4) thereby making possible to tailor the grating structural parameters to the desired bandwidth of the filter response without significantly affecting the tunability of the filter. Within the resonant structure (1) of the present invention, the core layer, i.e., the waveguide (4), can be placed close to the tunable layer (5), either in direct contact with the tunable layer or with an interposed relatively thin intermediate layer(s) between the core and the tunable layer. Proximity of the core layer (4) to the tunable layer (5) implies that the propagation mode can significantly extend into the tunable layer (5) so that the effective refractive index of the fundamental mode in the waveguide (4) is efficiently affected by variations of the refractive index of the tunable layer (5). ® KIPO & WIPO 2007

Title: A method and apparatus for providing quality of service to voip over 802.11 wireless lans
Inventor: ARUP ACHARYA
IPC: H04W74/06
Filed: 2003-11-26
Abstract: The present invention provides a method and system for providing quality-of-service to VoIP over a wireless local access network by providing periodic, contention-free access to a wireless link for voice packets. This is achieved by coupling Session Initiation Protocol ("SIP") signaling for call setup with the Point Coordination Function mode of operation of the 802.11 medium access control. The result is that VoIP call signaling via SIP is tied with availability of periodic time-slots on the wireless medium. The periodic time-slots are used to guarantee contention-free access to the wireless link for voice packets. Accordingly, the present invention, in effect, merges two networking technologies: SIP-based VoIP and 802.11-based wireless LANs.
