Optical injection locking of BARITT oscillators
Abstract
The first experimental results on optical injection locking are presented. A simple first-order locking theory is found to give reasonable agreement with measurements. The measured locking bandwidths are found to be approximately 50 percent larger than the calculated bandwidths. This is traced to the fact that the simple theory does not allow for an optical modulation of the device admittance (Y sub D) and its influence upon the locking characteristics. The locking bandwidth of approximately 0.6 percent as obtained with BARITT oscillators is found to be similar to the bandwidths predicted for IMPATT oscillators and transistor oscillators. It is shown experimentally that optical injection locking of BARITT oscillators is possible. It is noted that the locking bandwidth obtained (0.6 percent) may be viewed as a useful value.
