Photodetectors often limit the performance of RF-photonic systems. Signal distortion at high powers and shot noise at low powers can limit the dynamic range. Modeling photodetectors with sufficient accuracy and efficiency to make design optimization possible is a challenge. Join the OSA Photonic Detection Technical Group for this webinar with Curtis Menyuk presenting work done at the University of Maryland Baltimore County in modeling photodetectors and outlining future work aimed at using intelligent optimization of the device parameters.
The webinar will discuss the University of Maryland Baltimore County’s work developing models based on the drift-diffusion equations in collaboration with researchers at the Naval Research Laboratory. These models provide an excellent tradeoff between accuracy and efficiency. These models have been modified to include many important real-world effects and have demonstrated excellent agreement with experiments when the photodetectors operate in continuous-wave and pulse modes for both p-i-n and modified uni-travelling-carrier (MUTC) photodetectors.
