Application Note: Room-temperature Micro-electroluminescent Characterization of Ge-based IR Sources
23 December 2017
Monolithic integration of optical components on CMOS platforms is ongoing in the optical communications industry. CMOS offers a mature and robust platform, and therefore is logical for building optical-interconnect modules. These modules include light sources, modulators, multiplexers, and detectors on a single substrate. Silicon is the foundational material for CMOS technology, but as a material with an indirect bandgap, it poses a serious obstacle to building light sources via CMOS-based integrated photonics.
