Journal ArticleDOI
Proton exchange for high‐index waveguides in LiNbO3
TL;DR: In this article, the fabrication and characterization of optical waveguides formed in LiNbO3 by proton exchange in benzoic acid melts at 200-250°C is described.
Journal ArticleDOI
Dispersion penalty reduction using an optical modulator with adjustable chirp
Alan H. Gnauck,Steven K. Korotky,J.J. Veselka,J. Nagel,C.T. Kemmerer,W. J. Minford,D.T. Moser +6 more
TL;DR: In this paper, the value of the modulation chirp parameter that minimizes the transmission power penalty caused by fiber chromatic dispersion was experimentally identified using a unique Ti:LiNbO/sub 3/ modulator.
Journal ArticleDOI
Optical intensity modulation to 40 GHz using a waveguide electro‐optic switch
TL;DR: In this paper, the authors reported the intensity modulation of an optical carrier at frequencies as high as 40 GHz using a Ti:LiNbO3 optical waveguide switch and a self-electrooptic sampling technique was used to observe the modulation.
Journal ArticleDOI
A multiwavelength source having precise channel spacing for WDM systems
J.J. Veselka,Steven K. Korotky +1 more
TL;DR: In this paper, a combination of a periodically driven Mach-Zehnder modulator and a nonlinear fiber is used to generate an optical spectrum that consists of several wavelength components precisely spaced by 64 GHz (>0.5 nm).
Journal ArticleDOI
1 Gbit/s PSK homodyne transmission system using phase-locked semiconductor lasers
TL;DR: In this article, a 2/sup 15/-1 pseudorandom binary sequence (PRBS) has been transmitted through a short fiber with a receiver sensitivity of -44.2 dBm or 72 photons/bit.
