Patent number: 9316592Abstract: Light-emitting intra-cavity interferometric (ICI) optical sensors based on channel waveguide structures which include an internal light emitting material and a functionalized region. In some embodiments, the waveguides are made of a sol-gel which incorporates the light emitting material. In some embodiments, the waveguide structure includes an ICI resonator backbone and the ICI sensor is a laser sensor. In some embodiments, the resonator backbone has an interferometric Y-branch shape. In some embodiments, the resonator backbone has a Mach Zehnder interferometer shape. In some embodiments, an ICI laser sensor has an interferometric arrayed waveguide grating shape. In some embodiments, an ICI sensor may be remotely optically pumped and remotely read.Type: GrantFiled: June 3, 2012Date of Patent: April 19, 2016Assignee: Tel Aviv University Future Technology Development Ltd.Inventors: Asher Peled, Menachem Nathan, Shlomo Ruschin, Yifaat Betzalel, Judith Rishpon

Publication number: 20070196043Abstract: A biological or chemical optical sensing device comprises at least one planar micro-resonator structure included in a light emitting waveguide, and at least one biological or chemical probe bound to at least a part of the micro-resonator structure, the probe operative to bind specifically and selectively to a respective target substance, whereby the specific and selective binding results in a parameter change in light emitted from the waveguide. In one embodiment, the micro-resonator is linear. In some embodiments, the sensing device is active, the waveguide including at least one photoluminescent material operative to be remotely pumped by a remote optical source, and the parameter change, which may include a spectral change or a quality-factor change, may be remotely read by an optical reader.Type: ApplicationFiled: May 5, 2005Publication date: August 23, 2007Applicant: TEL AVIV UNIVERSITY FUTURE TECHNOLOGY DEVELOPMENT LTD.Inventors: Asher Peled, Menachem Nathan, Shlomo Ruschin, Tali Zohar
