[IEEE 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Kyoto, Japan (2018.7.9-2018.7.13)] 2018 31st International Vacuum Nanoelectronics Conference (IVNC) - Commutable cold cathodes based on vertically aligned carbon nanotubes with a buried modulation electrode
摘要： A new design of commutable CNT emitters cathode with an on-chips gate has been investigated. Both fabrication and field emission proprieties of a buried gate cathode have been demonstrated. Current modulation by applying a small bias on the buried gate has been performed. This design shows excellent modulation properties and a high robustness.

[IEEE 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Huangshan, China (2019.8.5-2019.8.8)] 2019 18th International Conference on Optical Communications and Networks (ICOCN) - Design of a current modulation driver for an ultra-compact RGB laser
摘要： RGB lasers have been widely used as light sources in projectors, endoscopes, HUD(Head up Displays) and many other displays. In this study, we designed a current driver circuit for an ultra-compact RGB laser, which allows for high speed driving current modulations. This characteristic is suitable for scanning display in many occasions. The laser current driver circuit is consisted of the current driver and the temperature controller. The current driver has three independently high-speed current modulation channels. We have tested the P-I performance of the RGB laser and the highest current modulation speed is 1.55MHz.
