“…By changing the spectral filter, we could easily change the observation spectral band during the same night as clearly shown by Berger et al (2001). We could also separate the spectral bands by using a bulk dichroic at the IO chip output or by using a dichroic function on the chip (Magerand et al 1994;Mestric et al 1996). For this purpose, using off-axis parabola for light injection in components is an attractive solution to overcome the limited single-mode range of the injection fibers.…”

Abstract.We report laboratory and on sky characterizations of planar integrated optics beam combiners in the K ([2.0 µm; 2.4 µm]) and K ([2.02 µm; 2.30 µm]) bands. Because of the strong scientific interests of the K band, we have extended the integrated optics technologies available in the telecom range (i.e. at 0.8 µm, 1.3 µm and 1.5 µm) to 2.0-2.5 µm. Ion exchange components optimized for these atmospheric bands provide stable contrasts higher than 95% with a laboratory white-light source and global throughputs of 35% in this spectral range. These results are completed with first stellar interferograms obtained with a silica-on-silicon two-way beam combiner on the IOTA interferometer. We characterized in the H and K bands the throughput of this beam combiner optimized for the H band ([1.47 µm; 1.78 µm]). On-sky fringes obtained on ιAur in the H and K bands clearly demonstrate a high instrumental contrast (larger than 50%) in both bands. This shows that integrated optics works with high performance outside its usual wavelength domain and provides good solutions for astronomical interferometry in a large wavelength range. We have measured single-mode ranges over 1 µm on our components which would allow to observe in two spectral bands simultaneously or to integrate both metrology reference and science signals in a single chip for astrometric applications.

“…However, with the ever-increasing demand of integration and miniaturization, the need for smaller and compact optical components also increases. Various efforts have been undertaken to realize DOI: 10.1002/lpor.202000556 compact spectrometers in different device configurations such as grating spectrometers, [5,6] array-waveguide gratings, [7,8] photonic-crystal based spectrometers, [9,10] superprism-based spectrometers, [11] and microring-based spectrometers. [12] In many of the aforementioned configurations, the spectral resolution is highly dependent on the angular distribution and effective optical path travelled by the light, requiring relatively large footprint devices to achieve a high-resolution spectrometer.…”

Integrated optical sensors have garnered much interest for lab-on-chip applications such as chemical and biological sensing and detection. Among various ways for detection schemes, spectral analysis performed by a spectrometer has shown great promise. Typically, such spectrometry is carried out in a relatively large device, owing to the fact that spectral resolution is often dictated by large optical path length. Here, a high-resolution compact spectrometer utilizing random scattering events in a disordered medium is demonstrated. The spectrometer is inverse designed by objective-first method and fabricated using two-photon polymerization technique. The compact spectrometer consists of a disordered photonic structure and an inversed-designed mode decomposer. A spectral resolution of 0.25 nm with a bandwidth of 30 nm in the near-infrared regime is realized from a spectrometer occupying a relatively small footprint of 30 × 12.8 µm 2 . The proposed platform has a great potential to be used as a versatile lightweight and compact spectrometer for various applications including on-chip spectrometer and sensing.
