Abstract
Lateral current injection (LCI) type membrane distributed feedback (DFB) lasers, proposed as light sources for on-chip optical wiring in LSIs, were theoretically investigated from aspects of low power consumption operation and high-speed direct modulation capability. It was confirmed that the LCI-membrane-DFB laser can be a good candidate for a low-pulse-energy (100 fJ/b) light source at high-speed operation (10 Gb/s), but the series resistance was found to be an important issue for low power consumption operation as well as a small footprint.
