Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

A 300-mm silicon photonics platform for large-scale device integration was developed,
leveraging 40-nm complementary metal-oxide-semiconductor technology. Through …

Convolutional neural networks (CNNs) have shown great performance in computer vision
tasks, from image classification to pattern recognition. However, CNNs′ \rmCNNs …

Arrayed waveguide gratings with reusable delay lines (RDL-AWGs) are demonstrated as
high resolving power integrated photonic spectrometers. One of the devices is 71 times …

We introduced shallow-etched silicon nanowire into the arrayed waveguides to decrease
the random phase error due to the core width fluctuation. A fairly improved crosstalk value of …

Spectrally dispersed light from a fine resolution waveguide grating router (WGR) of 25-GHz
free spectral range that radiates to free space is spatially filtered at∼ 1 GHz optical …

We analyze the performance of a spatial fiber switching system when using a pixelized
mirror, such as a LCoS or MEMS spatial light modulator, in place of a large tilting …

Earlier it was observed that polarization rotation in an AWG built from birefringent
waveguides can result in sidelobes in its response. This effect was measured in a …

Photonic crystals (PCs) are a promising technology for the realization of high-density optical
integrated circuits. PC-based couplers have been proposed as a compact means of …

A paper by Miller in 1969 [1] describes what was then called 'a miniature form of laser beam
circuitry'. It describes an idea to combine lasers with modulators and dielectric waveguides …
