Friebele E, Askins C, Shaw C, Gingerich M, Harrington C, Griscom D, et al.
Appl Opt . 2010 Aug; 30(15):1944-57. PMID: 20700162
Statistically significant correlations have been established between certain fabrication parameters of matched clad, single-mode optical fiber waveguides and their response to an ionizing radiation dose of 2000 rad. The reCOVE:ry...

Paek U, PETERSON G, Carnevale A
Appl Opt . 2010 Apr; 21(19):3430-6. PMID: 20396253
Parametric studies were done on the propagation characteristics of single-mode fiber using measured refractive-index profile data. Two types of profile were considered--a graded-index core with a depressed cladding (Delta' <...

Paek U, PETERSON G, Carnevale A
Appl Opt . 2010 Apr; 21(4):704-9. PMID: 20372521
Based on a set of exact vector form solutions to Maxwell's equations for optical waveguides, we studied the parametric effects on propagation characteristics of the HE(11) mode, varying the lightguide...

Paek U, Schroeder C
Appl Opt . 2010 Apr; 20(23):4028-34. PMID: 20372319
A newly designed 7.3-m high tower is reported that is equipped with a 10-kW curing system capable of coating a fiber with 50-microm thickness of UV curable resin at a...

Paek U, Schroeder C
Appl Opt . 2010 Mar; 20(7):1230-3. PMID: 20309290
The UV flux density required for photopolymerization is calculated, primarily based on an estimation of the overall system efficiency and the activation energy of the photoinitiator added to the prepolymer...

Paek U, Weaver A
Appl Opt . 2010 Feb; 14(2):294-8. PMID: 20134882
A study was made of the use of a CO(2) laser for producing a hemispherical lens at the end of a fiber. When the fiber end is heated to the...

Paek U
Appl Opt . 2010 Feb; 13(6):1383-6. PMID: 20126202
A system consisting of a cw CO(2) laser and an ellipsoidal reflector was developed in order to draw fused silica fibers from bulk material. The system was used to obtain...

Gagliano F, Paek U
Appl Opt . 2010 Feb; 13(2):274-9. PMID: 20125974
A high speed framing camera was used to record the sequential steps of the start, development, and cessation of a highly energetic plume of matter caused by a ruby laser...

Islam M, Soccolich C, Chen C, Paek U, Schroeder C, DiGiovanni D, et al.
Opt Lett . 2009 Sep; 16(8):593-5. PMID: 19774009
The timing restrictions for soliton-dragging logic gates can be relaxed by asymmetrizing the interaction between the orthogonally polarized control and signal pulses. In particular, by prechirping the signal pulse in...

Islam M, Soccolich C, Gordon J, Paek U
Opt Lett . 2009 Sep; 15(1):21-3. PMID: 19759698
We show experimentally and numerically that intensity-dependent polarization rotation does not lead to pulseshape distortions for fundamental solitons because the soliton rotates as a unit. We demonstrate an optical limiter...
