Modeling of Semiconductor Optical Amplifiers for Interferometric Switching Applications

Abstract
Summary form only given. Various applications of all-optical signal processing, e.g, demultiplexing in optical time-division multiplexing (OTDM) systems or optical sampling, can be accomplished by all-optical switches based on semiconductor optical amplifiers (SOAs) in interferometric configurations. To optimize such switching devices, it is useful to have a model which describes the temporal characteristics of the switches accurately. The SOA model, which we present, takes the pulse propagation and the gain dynamics into account. The gain dynamics is determined by carrier density modulation (also called carrier density pulsation, CDP) and carrier heating (CH), calculated in separate rate equations.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
