Fast tuning of a new evanescent-mode cavity tuner is demonstrated to optimize amplifier device power-added efficiency in simulations. The tuning is accomplished by adjusting the two resonant frequencies of the two-element tuner network with a modified interval halving approach. The tuner model is used to adjust the load impedance presented to a power amplifier device. Simulation results show that...
To lower the overall cost of an optical cavity biosensor, while still taking advantages of highly sensitive Fabry-Perot based optical cavity structures, we have proposed the use of two low cost, off-the-shelf laser diodes and employ a scaled differential calculation method instead of monitoring the intensity changes of a single laser diode. This paper describes three of the benefits of using the scaled...
