Patent number: 8649650Abstract: The present invention provides a method of making rare earth (RE) doped optical fiber using BaO as co-dopant instead of Al or P commonly used for incorporation of the RE in silica glass by MCVD and solution doping technique. The method comprises deposition of particulate layer of GeO2 doped SiO2 with or without small P2O5 for formation of the core and solution doping by soaking the porous soot layer into an aqueous solution of RE and Ba containing salt. This is followed by dehydration and sintering of the soaked deposit, collapsing at a high temperature to produce the preform and drawing of fibers of appropriate dimension. The use of Ba-oxide enables to eliminate unwanted core-clad interface defect which is common in case of Al doped fibers. The fibers also show good RE uniformity, relatively low optical loss in the 0.6-1.6 ?m wavelength region and good optical properties suitable for their application in amplifiers, fiber lasers and sensor devices.Type: GrantFiled: March 29, 2010Date of Patent: February 11, 2014Assignees: Council of Scientific & Industrial Research, Department of Information TechnologyInventors: Ranjan Sen, Anirban Dhar, Mukul Chandra Paul, Himadri Sekhar Maiti

Publication number: 20110249557Abstract: The present invention is an implementation of a network device called Wireless Manager (WiM) a centralized controller for QoS management of infrastructure WLANs based on the IEEE 802.11 DCF standards. The WiM queues and schedules packets from all the traffic flowing between the Access Points (APs) and the wireline LAN which requires no changes to the AP or the STAs, and can be viewed as implementing a Split-MAC architecture. The objectives of WiM are to manage various TCP performance related issues such as the throughput anomaly when STAs associate with an AP with mixed PHY rates, and upload download unfairness induced by finite AP buffers, and also to serve as the controller for VoIP admission control and handovers, and for other QoS management measures.Type: ApplicationFiled: November 12, 2009Publication date: October 13, 2011Applicants: Indian Institute of Science, Department of Information TechnologyInventors: Hedge Malati, Kumar Pavan, K.R. Vasudev, S.V.R. Anand, Kumar Anurag, Kuri Joy
