Show Abstract
We report for the first time switching and modulation of light in a magneto‐optic waveguide that is a single‐crystal epitaxially grown iron‐garnet film. These experiments involve the Faraday rotation of the magnetic film and the motion of magnetization in the plane of the film. We have modulated light from a 1.152‐μm laser up to 80 MHz. We were also able to switch light between two waveguide modes by applying a magnetic field as small as 0.2 Oe.

Electromigration in conductor stripes under pulsed dc powering

Show Abstract
Thin Ti☒Au films on sapphire were powered using pulsed dc. The incidence of electromigration damage is a complex function of pulse duration and repetition rate. For a given total ``exposure'' (fixed current density for a fixed total on‐time) the damage may be reduced or eliminated by using duty cycles less than 100%.

Microwave Kerr effect on polar liquids

M. Najim, J.C. Matheau, and S. Lefeuvre

Appl. Phys. Lett. 21, 399 (1972); http://dx.doi.org/10.1063/1.1654429 (2 pages)

Show Abstract
It is possible under some restrictive conditions on the choice of dielectric materials to show and measure Kerr effect at microwave frequencies. The quadratic Kerr law is verified and the Kerr constant is calculated in the X‐band for tri‐o‐cresylphosphate and cyclohexanol.

Noncollinearly phase‐matched second‐harmonic generation in LilO3

Shinsuke Umegaki, Seiichi Yabumoto, and Shun‐ichi Tanaka

Appl. Phys. Lett. 21, 400 (1972); http://dx.doi.org/10.1063/1.1654430 (3 pages) | Cited 3 times

Show Abstract
Efficient second‐harmonic generation of light, where the wave‐vector‐matching condition is satisfied noncollinearly or two‐dimensionally, has been observed using a Nd:YAG laser as a fundamental and LiIO3 as a nonlinear crystal. The phase‐matching condition has been found to be satisfied in a wide range of the angle around the optic axis of the crystal.
