Abstract

A demonstration of the effect of tuning components on a directly modulated distributed feedback laser (DFB) high-frequency performance is shown in this paper. A network based on three inductors and a microstrip line is used to impedance match the parasitic reactance of a laser diode within a tuning bandwidth. The matching and transmission performance of the laser under these conditions is compared with a radio frequency network simulation that include the intrinsic model of the DFB laser with its internal parasitic reactance, and the added external microstrip components.

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
