OPA Winners
This year, two outstanding papers were selected for recognition:
“
High-Power Distributed Bragg Reflector Lasers for Green-Light Generation ”
Martin H. Hu, Hong Ky Hguyen, Kechang Song, Yabo Li, Nick J. Visovsky, Xingsheng Liu, Nobuhiko Nishiyama, Sean Coleman, Lawrence C. Hughes Jr., Jacques Gollier, William Miller, Raj Bhat, and Chung-En Zah; Proceedings of SPIE – Optical Components and Materials III, Vol. 6116, pp. 61160M-1; 2006
This paper reports world-class results for high output power, compact green lasers, based on Corning’s semiconductor laser technology. Corning’s scientists and engineers demonstrated a novel green laser based on second harmonic generation of 1060 nm semiconductor laser emission, with high output power and compact size. Corning’s green laser is of interest as a keystone component needed for red-green-blue projection displays.
Abstract:
We report on the design, fabrication and performance of high-power and high-modulation-speed 1060-nm DBR lasers for green-light emission by second harmonic generation. Single-spatial-mode and single-wavelength power more than 450 mW of 1060-nm wavelength was achieved with a 3-section DBR laser with non-absorbing DBR and phase sections created by an impurity-free quantum-well intermixing technique. A thermally-induced wavelength tuning of 2.4 nm and a carrier-induced wavelength tuning of –0.85 nm were obtained by injecting current into the DBR section. The green power as high as 104.6 mW was demonstrated by coupling the DBR laser output to a second-harmonic-generation waveguide. Measured rise/fall times of 0.2 ns for direct intensity modulation and 0.6 ns for wavelength modulation make the DBR lasers suitable for >=50-MHz green-light-modulation applications. The detrimental thermally-induced patterning effect and a differential-phase modulation scheme as a solution are discussed.

Light-cured acrylic materials are ideal for use in a wide variety of applications, including inks, adhesives, packaging materials, and protective coatings for optical fibers. This paper is an excellent example of Corning’s interdisciplinary R&D approach which enabled the improved understanding of the complex interplay between chemical reactions and physical restraints taking place during the photopolymerization process.
Abstract:
An integrated approach, involving the use of a number of analytical techniques, was used to study polymer coating network development during photopolymerization of a series of fast reacting, low modulus coating formulations containing urethane/acrylate oligomers and acrylic comonomers. Real-time UV rheology measurements, to assess the development of viscoelastic properties, and real-time FTIR, to assess the disappearance of acrylic groups, were used to study the early stages of the photocuring reaction up to the gel point. These results showed that the development of the cross-linked network and the rate at which acrylate double bonds reacted were not necessarily directly proportional as might be expected and were dependent upon the structures of the urethane/acrylate oligomer and comonomers comprising a particular coating. Samples of partially polymerized coatings were also prepared having degrees of acrylate conversion ranging from ~50% through full conversion. Analysis of the amount of extractable material and the molecular weight distribution of soluble oligomeric material as a function of degree of conversion also showed a dependence upon the coating formulation components. In some cases the extraction results for intermediate cure level samples could be correlated to the reactivity trends observed in the early stages of the curing reaction. We also made use of solid-state NMR 1H T2 relaxation measurements to assess both partially and fully reacted films. The rate of magnetization decay correlated well with both the developing level of cross-link density as the degree of polymerization increased and also with the theoretical cross-link densities expected for the fully cured networks based on the structure of the coating formulation components. The latter also correlated well with modulus measurements made on fully cured coating film samples.
