摘要

我们展示了一种基于混合导波和自由空间光学系统的新型光谱仪，该系统由氮化硅光学相控阵(OPA)，自由空间光栅耦合器和图像传感器的傅里叶空间成像组成。每一个被光子集成电路分散的波长在傅里叶平面上对应一个独特的位置。我们演示了从该平面的位置和强度重建近红外光谱。通过对小型OPA (0.1 mm2)的初步测量，我们报告了100 nm的光谱范围和0.5 nm左右的分辨率。

On-chip silicon nitride optical phased array as a broadband near-infrared spectrometer

We demonstrate a novel spectrometer based on a hybrid guided wave and free-space optical system, consisting of a silicon nitride optical phased array (OPA), free-space grating couplers, and Fourier-space imaging to an image sensor. Each wavelength dispersed by the photonic integrated circuit corresponds to a unique position in the Fourier plane. We demonstrate the reconstruction of a spectrum in the near-infrared from the position and the intensity in this plane. From preliminary measurements on a small-sized OPA (0.1 mm2), we report a spectral range of 100 nm and a resolution of around 0.5 nm.

期刊介绍： Opto-Electronics Review is peer-reviewed and quarterly published by the Polish Academy of Sciences (PAN) and the Association of Polish Electrical Engineers (SEP) in electronic version. It covers the whole field of theory, experimental techniques, and instrumentation and brings together, within one journal, contributions from a wide range of disciplines. The scope of the published papers includes any aspect of scientific, technological, technical and industrial works concerning generation, transmission, transformation, detection and application of light and other forms of radiative energy whose quantum unit is photon. Papers covering novel topics extending the frontiers in optoelectronics or photonics are very encouraged. It has been established for the publication of high quality original papers from the following fields: Optical Design and Applications, Image Processing Metamaterials, Optoelectronic Materials, Micro-Opto-Electro-Mechanical Systems, Infrared Physics and Technology, Modelling of Optoelectronic Devices, Semiconductor Lasers Technology and Fabrication of Optoelectronic Devices, Photonic Crystals, Laser Physics, Technology and Applications, Optical Sensors and Applications, Photovoltaics, Biomedical Optics and Photonics
