Abstract:
High-performance waveguide-integrated Ge/Si APDs in separate absorption, charge, and multiplication (SACM) schemes have been exploited to facilitate energy-efficient optical communication and interconnects. However, the charge layer design is complex and time-consuming. A waveguide-integrated Ge/Si avalanche photodetector (APD) is proposed in a separate absorption and multiplication (SAM) configuration. The device can work at low voltage and high speed with a lateral multiplication region without complexity of the charge layer. The proposed device is implemented by the complementary metal-oxid

Low-frequency and 1/f noise are common measurement limitations that arise in a variety of physical processes. Mitigation methods for these noises are dependent on their source. Here, we present a method for removing 1/f noise of optical origin using a micro-cavity Fabry–Pérot (FP) interferometer. A mechanical modulation of the FP cavity length was applied to a previously studied opto-mechanical sensor. It effectively mimics an up-conversion of the laser frequency, shifting signals to a region where lower white-noise sources dominate and 1/f noise is not present. Demodulation of this signal shi

Single-walled carbon nanotubes (SWCNTs) have a number of unique properties that are attractive for emerging opto-electronic technologies. Among these is chirality, an important property of both natural and synthetic systems. A chiral object is not superimposable with its mirror-image reflection, and an object has handedness if it exists as two enantiomers that can be viewed as “left-handed” and “right-handed” mirror-image pairs. In the past couple of decades, chirality has emerged as a potentially powerful way to manipulate spin transfer and transport, via the so-called chirality-induced spin

Simulation of LR driving and operation scenarios in isolation studies is a way to get a more insight in the type of operations to be performed on the Moon and to update the virtual control model as novel navigation and positioning technologies appear.
