PCA-Boosted Autoencoders for Nonlinear Dimensionality Reduction in Low Data Regimes
Muhammad Al-Digeil, Yuri Grinberg, Daniele Melati3 +5
Autoencoders (AE) provide a useful method for nonlinear dimensionality reduction but are ill-suited for low data regimes. Conversely, Principal Component Analysis (PCA) is data-eff…
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…
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…
Isolator-free Integration of C-band InAs-InP Quantum Dash Buried Heterostructure Lasers with Silicon Waveguides
Jens H. Schmid, Mohamed Rahim, Grzegorz Pakulski +9
An InAs-on-InP quantum dash buried heterostructure laser and silicon chip optimized for mutual integration by direct facet-to-facet coupling have achieved -1.2 dB coupling efficien…
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…
