An optical sensor includes an optical coupler. The optical sensor further includes a photonic bandgap fiber having a hollow core and an inner cladding generally surrounding the core. The photonic bandgap fiber is in optical communication with the optical coupler.
An optical device and methods of using an optical device are provided. The optical device includes a hollow-core fiber including a first portion and a second portion. The first portion includes a hollow core having a first diameter.
An optical device comprising: a first hollow-core photonic-bandgap fiber portion configured to transmit light having a wavelength, wherein the first portion has a first longitudinal axis and is configured to be adjustably twisted about the first longitudinal axis by a torque a
Stanford researchers have developed novel systems and methods for power-controlled shared channel access in wireless networks supporting packetized data traffic.
This patented invention is an internet-based laboratory data management system that can be used to create protocols, collect and organize data, archive long-term records, and facilitate scientific collaboration among researchers.
Proxy Identity Based Encryption (proxy IBE) is a new encryption scheme that allows a user to send data encrypted with any given public key to a receiving user who decrypts the data with their own private key which is of no relation to the key used for encryption.
Stanford researchers in John Cioffi's lab have developed a method for allocating resources (bit rate and transmit power) in multi-user, multi-carrier communication systems. The invention provides the optimal power allocation algorithm for the equal-length DSL loops.
Stanford researchers have created software to view panoramic videos from arbitrary viewpoints from separate non-overlapping geo-referenced panoramic video streams. Ths system can also synthesize missing panoramic images to provide the user with a full sequence.
This user interface enables a user to define tags within virtual tour applications that label objects in panoramic images and video – a process that has been very difficult to achieve prior to this invention.
Stanford researchers in John Cioffi's lab have developed a method and apparatus for controlling the data rate in the uplink of a Code Division Multiple Access (CDMA)/ Orthogonal Frequency Division Multiplexing (OFDM) system.
Researchers in the Herzenberg lab at Stanford have developed and patented a federated directory service system for managing scientific data. Scientific data is often stored in paper-bound notebooks and unstructured computer files which can be difficult to maintain over time.
