Abstract
The self-scanning light-emitting device (SLED) is expected to become a new key device for two-dimensional optical information processing, because the light-emitting ON-states of the SLED are automatically transferred by input clock pulses, and the optical pulses can start the transfer action from any elements. It will be important to decrease the number of transfer clock lines in order to realize the highly packed two-dimensional integrated SLED. Therefore, we propose the two-phase drive SLED using coupling diodes and demonstrate its operation. It has a wide operating margin as well as 10 MHz as the maximum transfer frequency.Keywords
