Methods For Fabricating Lenses At The End Of Optical Fibers In The Far Field Of The Fiber Aperture

View page
US Patent:
7128943, Oct 31, 2006
Filed:
Feb 20, 2003
Appl. No.:
10/369993
Inventors:
Nicholas Djeu - Tampa FL, US
Assignee:
University of South Florida - Tampa FL
International Classification:
B05D 5/06
US Classification:
427162, 4271631, 4271632, 427240, 427512, 427513, 427516, 427508, 118 52, 118 56, 385 33, 385 34, 385 35
Abstract:
A microlens is affixed in the far field of an optical fiber to spatially transform a beam either entering or exiting the fiber. In a first embodiment, a droplet of photo polymer is placed on the end of an optical fiber and the fiber is spun to create an artificial gravity. The droplet is cured by UV radiation during the spinning. In a second embodiment, nanoparticles are mixed into the droplet to increase the refractive index of the photo polymer. A third embodiment employs artificial gravity to attach a microsphere to the end of the optical fiber. A fourth embodiment chemically treats the surface of the microsphere so that the requirement of artificial gravity is either reduced or eliminated. In a fifth embodiment the droplet is cured under equlibrium or nonequilibrium conditions to obtain different final shapes for the lenslet. A sixth embodiment discloses fabrication of microlens arrays.

Combined Fiber-Optic Absorption And Emission Measurement Apparatus

View page
US Patent:
7855780, Dec 21, 2010
Filed:
Jun 13, 2008
Appl. No.:
12/139015
Inventors:
Nicholas Djeu - Tampa FL, US
Assignee:
University of South Florida - Tampa FL
International Classification:
G01N 21/65
G01N 21/35
US Classification:
356 73, 356301, 25033907
Abstract:
Disclosed is a spectroscopic system having a fiber-optic probe for simultaneous IR and Raman measurement. The probe includes a single strand of optical fiber, such as sapphire which is suitable for IR absorption measurements as far as 4 μm and Raman excitation at wavelengths as short as 300 nm. The probe is immersed in the sample and functions in the evanescent wave mode for both IR absorption and Raman scattering measurements. The sensing system makes possible the synergistic, and simultaneous, analysis of both IR and Raman data in an integrated device.

US Patent:
8592768, Nov 26, 2013
Filed:
Apr 6, 2010
Appl. No.:
12/755093
Inventors:
Nicholas Djeu - Tampa FL, US
Assignee:
University of South Florida - Tampa FL
International Classification:
G01J 5/02
G02B 6/00
G02B 6/42
G02B 6/32
G01N 21/47

Microcavity Raman Sensor And Method Of Use

View page
US Patent:
8599373, Dec 3, 2013
Filed:
Jul 5, 2012
Appl. No.:
13/542282
Inventors:
Nicholas Djeu - Tampa FL, US
Andreas Muller - Tampa FL, US
Assignee:
University of South Florida - Tampa FL
International Classification:
G01J 3/44
US Classification:
356301, 356300
Abstract:
In accordance with the present invention, an ultra-sensitive Raman chemical sensor is provided that is based on an enhanced spontaneous emission as a result of cavity quantum electrodynamic effects. More specifically, the sensor in accordance with the present invention makes use of a double resonance of a microcavity with both the excitation laser frequency and the Raman frequency. As such, the Raman shift corresponds to an integer times the free spectral range of the microcavity. Because the Raman frequency directly depends on the excitation laser's frequency, the fulfillment of the resonance condition for the excitation laser frequency guarantees that resonance with the Raman frequency is also satisfied.
