Abstract
A novel design geometry for an optically pumped LED by integrating thin III-V membranes
on SOI is proposed. The depicted device consists of a silicon waveguide feeding a
high refractive index contrast III-V membrane waveguide. Several simulation tools were
used to optimize the design of the coupler, the absorption properties of the pump, the
collection efficiency of the generated spontaneous emission and the heat properties of the
membrane. Combined these simulation results predict a high power efficiency of the device,
while keeping the fabrication tolerances high. Following the simulation, we present
a first proof-of-concept demonstration of the LED. Related Research Topics
