Electric-field induced nonlinear optics in CMOS silicon nanophotonic waveguides
Abstract/Contents
- Abstract
- The microelectronics industry is foundationally built on silicon-based semiconductor devices. Silicon photonics, a relatively nascent yet rapidly emerging field, leverages the maturity of CMOS foundry processes and promises dense integration of optical functionality like that of microelectronic circuits. However, silicon's inability to produce optical gain or lase has presented a major barrier to developing fully integrated silicon-based optoelectronic devices. In parallel, nonlinear optics has made substantial advances in expanding the range of accessible frequencies of optical sources, yet as a field has evolved largely independently of silicon-based materials. By combining the principles of nonlinear optics with scalable, high-quality linear optical elements enabled by silicon photonics, such as waveguides, and electronic devices, such as CMOS-based diodes, all on-chip, the latitude of optoelectronic functionality of silicon can be significantly expanded. Although nonlinear optical processes such as sum frequency generation and optical parametric amplification are forbidden in silicon, due to its crystalline inversion symmetry, this symmetry can be broken with an applied electric field, a process known as electric field induced second harmonic generation, which is effectively derived from the third-order susceptibility of a material and can be understood as four-wave mixing between two optical electromagnetic fields, one DC field, and a resultant optical field at a harmonic frequency. Moreover, quasi-phase matching allows for efficient power transfer between these fields, which can be implemented at-scale in silicon using periodically-poled DC fields generated by reverse-biased PN diodes. In this thesis, I will discuss the design and characterization of devices that utilize industry-ready silicon photonics foundry processes to realize nonlinear optics on-chip via second harmonic generation and the first (second-order) optical parametric amplifier on silicon.
