Abstract
Modified uni-traveling carrier photodiodes offer world leading capabilities in terms of their power handling and linearity. For this reason, it is no surprise that they are an irreplaceable tool in RF Photonics, namely in RF Photonic links. As these devices develop further, applications for them will continue to grow, but not until significant advancements are made in their power handling capability. As of now, joule heating remains a factor not addressed within MUTC epitaxies which leads to thermal failure. ☐ In this work, developments are made on a new MUTC epitaxy which specifically addresses joule heating for the first time. Based on simulations from UVA, this epitaxy has the capability to increase dissipated power at failure, but to produce useful, functional devices from this epitaxy is an entirely new challenge. The process and considerations of making devices from this new epitaxy will be shown. As will be demonstrated, this epitaxy under the right conditions offers a promising future for increasing power handling capabilities.
