Electrical parasitics and parameter extraction of photonic crystal vertical-cavity surface-emitting lasers
… analysis. Impedance characteristics and electrical parasitics are studied for various photonic crystal designs to understand factors which limit high speed modulation. Photonic crystal designs are found to have low differential resistance, but high parasitic capacitance. By including a …

Thermal and Electrical Parasitic Modeling for Multi-Chip Power Module Layout Synthesis
<p><strong>This thesis presents thermal and electrical parasitic modeling approaches for layout synthesis of Multi-Chip Power Modules (MCPMs). MCPMs integrate power semiconductor devices and drive electronics into a single package. As the switching frequency of power devices increases, the size of …

CMOS circuits for VCSEL-based optical IO
Electrical IO is becoming limited by copper interconnect channel losses that depend on frequency and distance. Package-to-package optical interconnects see negligible frequency-dependent channel losses, but data rates are limited by the intrinsic optical dynamics and electrical parasitics of the …
