BACKGROUND Optical spectrometry is one of the most powerful and widely used
characterization tools in scientific and industrial research. Benchtop laboratory spectrometer …

Miniaturized optical spectrometers could be of use in portable and wearable applications.
Such devices have typically been based on arrays of photodetectors that provide distinct …

We demonstrate a 50-channel high-resolution arrayed waveguide grating
microspectrometer with a 0.2 nm channel spacing on a silicon-on-insulator (SOI) platform …

We propose a new type of arrayed waveguide grating (AWG) device that operates as a
Fourier-transform (FT) spectrometer without the need of scanning elements. The large input …

Miniature spectrometer is powerful tool for scientific research and industrial inspection. Here,
we report the fabrication of graded perovskite filters with tunable bandgap and their …

A novel Fourier spectrometer based on a partly transparent thin-film detector in combination
with a tunable silicon micromachined mirror was developed. The operation principle based …

Image sensors used in consumer cameras only detect intensity of light. Spectral, angular,
and phase information of incident light is largely lost. For conventional applications like …

We present the technological verification of a size-optimized 160-channel, 50-GHz silicon
nitride-based AWG-spectrometer. The spectrometer was designed for TM-polarized light …

This article presents an innovative high spectral resolution waveguide spectrometer, from
the concept to the prototype demonstration and the test results. The main goal is to build the …

Optical measurement is conducted by employing components such as a spectrometer or
photodiode (PD) to detect light intensity. However, the size of spectrometer is large because …
