Photonic devices monolithically integrated with nanoscale electronic signal processing circuitry in silicon are emerging as a disruptive technology to reduce cost and improve optical system integration and performance. Silicon heterojunction bipolar transistor (HBT)-based carrier injection electroabsorption modulators (EAMs) implemented in a commercial silicon process have several merits, including...
Hexagonal ferrites such as BaFe12O19 have very strong uniaxial anisotropic magnetic field and remanent magnetism. By employing these properties, magnetic devices can work in the tens of GHz frequency range without strong external magnetic field. The micro- and nano-sized hexagonal ferrite can be conveniently utilized to fabricate magnetic components integrated in CMOS integrated circuits. A circulator...
Monolithic optoelectronic integrated circuits are a primary focus of research for high-speed optical communication system development. Standard silicon processes provide a cost effective way for electro-optic system integration. This paper presents a monolithic optical modulator and driver design based on 130nm SiGe BiCMOS technology. Post-layout simulation results demonstrate that the modulator achieves...
