“…This type of spectrometer includes wavelength (de)multiplexers such as arrayed waveguide gratings (AWG), planar concave gratings (PCG), and micro-resonator arrays. It also encompasses those operating on the wavelength multiplexing principle such as spatial heterodyne spectrometer (SHS) [204]. To the best of the authors' knowledge, all on-chip mid-IR waveguide spectrometers demonstrated hitherto belong to this category (Table 6).…”

Abstract:The emergence of silicon photonics over the past two decades has established silicon as a preferred substrate platform for photonic integration. While most silicon-based photonic components have so far been realized in the near-infrared (near-IR) telecommunication bands, the mid-infrared (mid-IR, 2-20-μm wavelength) band presents a significant growth opportunity for integrated photonics. In this review, we offer our perspective on the burgeoning field of mid-IR integrated photonics on silicon. A comprehensive survey on the state-of-the-art of key photonic devices such as waveguides, light sources, modulators, and detectors is presented. Furthermore, on-chip spectroscopic chemical sensing is quantitatively analyzed as an example of mid-IR photonic system integration based on these basic building blocks, and the constituent component choices are discussed and contrasted in the context of system performance and integration technologies.

“…The mid-infrared (midIR) wavelength range is of particular interest for these applications due to the orders of magnitude higher optical absorption crosssection in this range as compared to the telecom and visible wavelength range [1][2][3][4]. Up to this point multiple platforms have been suggested for the implementation of midIR photonic integrated circuits (PICs), some of which are suspended Si membrane [5], silicon-on-sapphire (SOS) [6] and graded index GeSi platform [7] which also finds its application in non-linear photonics [8].…”

Abstract:We present the design, fabrication and characterization of efficient fiber-to-chip grating couplers on a Germanium-on-Silicon (Ge-on-Si) and Germanium-on-silicon-on-insulator (Ge-on-SOI) platform in the 5 µm wavelength range. The best grating couplers on Ge-on-Si and Ge-on-SOI have simulated coupling efficiencies of -4 dB (40%) with a 3 dB bandwidth of 180 nm and -1.5 dB (70%) with a 3 dB bandwidth of 200 nm, respectively. Experimentally, we show a maximum efficiency of -5 dB (32%) and a 3 dB bandwidth of 100 nm for Ge-on-Si grating couplers, and a -4 dB (40%) efficiency with a 3 dB bandwidth of 180 nm for Ge-on-SOI couplers.

“…As a waveguide platform, silicon-on-insulator (SOI) stands out for these applications because of the mature fabrication processes, large volume fabrication potential and the fact that compact photonic integrated circuits can be realized. In our previous work we have demonstrated passive SOI spectrometers operating over a wide wavelength range, from 1.5 μm till 3.85 μm [8][9][10][11]. The integration of GaInAsSb-based p-i-n photodiodes with a cut-off wavelength of 2.65 μm on this platform was also demonstrated [12][13][14].…”

Abstract:A compact (1.2 mm 2 ) fully integrated mid-IR spectrometer operating in the 3 μm wavelength range is presented. To our knowledge this is the longest wavelength integrated spectrometer operating in the important wavelength window for spectroscopy of organic compounds. The spectrometer is based on a silicon-on-insulator arrayed waveguide grating filter. An array of InAs 0.91 Sb 0.09 p-i-n photodiodes is heterogeneously integrated on the spectrometers output grating couplers using adhesive bonding. The spectrometer insertion loss is less than 3 dB and the waveguide-referred responsivity of the integrated photodiodes at room temperature is 0.3 A/W.
