Capacitively-Induced Free-Carrier Effects in Nanoscale Silicon Waveguides for Electro-Optic Modulation
Rajat Sharma, Matthew W. Puckett, Hung-Hsi Lin +3
We fabricate silicon waveguides in silicon-on-insulator (SOI) wafers clad with either silicon dioxide, silicon nitride, or aluminum oxide, and by measuring the electro-optic behavi…
Resonantly Trapped Bound State in the Continuum Laser
Thomas Lepetit, Qing Gu, Ashok Kodigala +3
Cavities play a fundamental role in wave phenomena from quantum mechanics to electromagnetism and dictate the spatiotemporal physics of lasers. In general, they are constructed by…
Transmission Enhancement of High- Waves through Metal-InGaAsP Multilayers Calculated via Scattering Matrix Method with Semi-Classical Optical Gain
Joseph S. T. Smalley, Felipe Vallini, Shiva Shahin +2
We analyze the steady-state transmission of high-momentum (high-) electromagnetic waves through metal-semiconductor multilayer systems with loss and gain in the near-infrared (N…
Silicon Nanoridge Array Waveguides for Nonlinear and Sensing Applications
Matthew W. Puckett, Rajat Sharma, Felipe Vallini +6
We fabricate and characterize waveguides composed of closely spaced and longitudinally oriented silicon ridges etched into silicon-on-insulator wafers. Through both guided mode and…
Characterizing the effects of free carriers in fully-etched, dielectric-clad silicon waveguides
Rajat Sharma, Matthew W. Puckett, Hung-Hsi Lin +2
We theoretically characterize the free-carrier plasma dispersion effect in fully-etched silicon waveguides, with various dielectric material claddings, due to fixed and interface c…
