Athermal and tunable echelle grating wavelength demultiplexers using a Mach-Zehnder interferometer launch structure
Daniele Melati, Dan-Xia Xu, Ross Cheriton +5
We present a comparative experimental study of three silicon photonic echelle grating demultiplexers that are integrated with a Mach-Zehnder interferometer (MZI) launch structure.…
Design of Compact and Efficient Silicon Photonic Micro Antennas with Perfectly Vertical Emission
Daniele Melati, Mohsen Kamandar Dezfouli, Yuri Grinberg +5
Compact and efficient optical antennas are fundamental components for many applications, including high-density fiber-chip coupling and optical phased arrays. Here we present the d…
Two-Photon Photocurrent in InGaN/GaN Nanowire Intermediate Band Solar Cells
Ross Cheriton, Sharif M. Sadaf, Luc Robichaud +3
Intermediate band solar cells hold the promise of ultrahigh power conversion efficiencies using a single semiconductor junction. Many current implementations use materials with ban…
Spectrum-free integrated photonic remote molecular identification and sensing
Ross Cheriton, Suresh Sivanandam, Adam Densmore +11
Absorption spectroscopy is widely used in sensing and astronomy to understand molecular compositions on microscopic to cosmological scales. However, typical dispersive spectroscopi…
Photonic Temperature and Wavelength Metrology by Spectral Pattern Recognition
Siegfried Janz, Ross Cheriton, Dan-Xia Xu +8
Spectral pattern recognition is used to measure temperature and generate calibrated wavelength/frequency combs using a single silicon waveguide ring resonator. The ring generates t…
