Wang, Y. et al. Silicon/III-V laser with super-compact diffraction grating for WDM applications in electronic-photonic integrated circuits. Optics Express 19, 2006–2013 (2011).
Abstract:
We have demonstrated a heterogeneously integrated III-V-on-Silicon laser based on an ultra-large-angle super-compact grating (SCG). The SCG enables single-wavelength operation due to its high-spectral-resolution aberration-free design, enabling wavelength division multiplexing (WDM) applications in Electronic-Photonic Integrated Circuits (EPICs). The SCG based Si/III-V laser is realized by fabricating the SCG on silicon-on-insulator (SOI) substrate. Optical gain is provided by electrically pumped heterogeneous integrated III-V material on silicon. Single-wavelength lasing at 1550nm with an output power of over 2mW and a lasing threshold of around 150mA were achieved.
