Device-Under-Test Jones Matrix Extraction Algorithm With Device TE/TM Reference Frame

Autor: D. B. Adams, Christi K. Madsen, Jaehyun Kim

Publikováno v: IEEE Photonics Technology Letters. 24:88-90

The Jones matrix measured with an optical vector analyzer (OVA) is the result of a cascade of individual Jones matrices representing the input fiber path, device under test (DUT), and output fiber path. To extract the DUT matrix, compensation of the

Compact Bends for Achieving Higher Integration Densities for LiNbO$_{3}$ Waveguides

Autor: Xin Xia, S. Grover, D. B. Adams, W. C. Tan, O. Eknoyan, Christi K. Madsen, Mehmet E. Solmaz

Publikováno v: IEEE Photonics Technology Letters. 21:557-559

A new waveguide platform is demonstrated that allows the bend radii to be substantially decreased for titanium-diffused lithium-niobate (LiNbO3) waveguides using vertically integrated arsenic-trisulfide (As2S3) overlay waveguides. Power is transferre

The effect of infection with the abomasal nematode, Haemonchus contortus, on the avoidance behaviour of sheep in a motivational-choice test

Autor: L. R. Fell, D. B. Adams

Publikováno v: International Journal for Parasitology. 27:665-673

The behaviour of immune and non-immune sheep infected with H. contortus and undergoing a variety of experimental treatments was investigated in a motivational-choice test, the arena test. This test evaluates motivational state in sheep by pitting the

Getting more on lithium niobate: Vertical integration

Autor: Robert A. Atkins, J. Simcik, D. B. Adams, Christi K. Madsen, Mehmet E. Solmaz

Publikováno v: 2009 IEEE Avionics, Fiber-Optics and Phototonics and Photonics Technology Conference.

The integration density on lithium niobate is limited by the low-index-contrast diffused waveguides. We summarize recent work on vertical integration of a high-index-contrast waveguide layer to enable U-bends and ring resonators with sub-mm bend radi

First Demonstration of an As2S3-on-LiNbO3 Ring Resonator

Autor: W. C. Tan, Xin Xia, S. Grover, Christi K. Madsen, D. B. Adams, Mehmet E. Solmaz, O. Eknoyan

Publikováno v: Optical Fiber Communication Conference and National Fiber Optic Engineers Conference.

A race-track ring resonator with a 600µm diameter and 25GHz free spectral range is demonstrated by vertically integrating arsenic-trisulfide (As 2 S 3 ) waveguides with Ti-diffused LiNbO 3 waveguides. Measurements of the TM ring resonator response a

Social organization of Merino sheep of different ages, sex and family structure

Autor: D. B. Adams, J.J. Lynch, Geoff N. Hinch, A. Stolba, H.I. Davies, R. K. Munro

Publikováno v: Applied Animal Behaviour Science. 27:337-349

Four different groups of Merino sheep were established and social interactions were examined in paddocks which were barren or with trees and other topographic features. Two groups had been established for 2 years. One group consisted of ewes of the s

Photonically-assisted RF signal processing

Autor: D. B. Adams, Mehmet E. Solmaz, Christi K. Madsen

Publikováno v: LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings.

Phase modulation and dispersive filters are key to optical time-frequency signal processing. Novel optical implementations will be discussed along with applications including time scaling, waveform complex spectrum measurement and optical wavelet pro

Fast amplitude and delay measurement for characterization of integrated optic devices

Autor: D. B. Adams, M. Thompson, W. Rivera, Christi K. Madsen, H. Zhu, Mehmet E. Solmaz

Publikováno v: SPIE Proceedings.

A fast, non-interferometric measurement technique that allows the frequency-dependent delay and amplitude responses to be measured is presented. For a single amplitude and relative phase measurement at a fixed optical wavelength, the measurement time

Boundless-range Phase Shifters and Sideband Reduction

Autor: D. B. Adams, Mehmet E. Solmaz, Christi K. Madsen, Michael Thompson

Publikováno v: Optical Amplifiers and Their Applications/Coherent Optical Technologies and Applications.

A boundless-range phase shifter is demonstrated at 10GHz using a dual parallel electro-optic modulator. Sideband and carrier rejections over 30dB are achieved using a coherent optical spectrum analyzer to verify the operation.
