“…Initial research in inverse design for nanophotonics focused on passive, linear devices on Silicon-on-Insulator (SOI) platforms. Recently, the approach has been extended to time-varying active devices [266][267][268], topological insulators [264], and nonlinear optics [263], as well as alternative substrates such as diamond [262]. In conclusion, inverse design for nanophotonics has demonstrated a strong track record for producing high-performance, compact, and robust devices in numerous different contexts and it has proven to be an invaluable tool for the photonics designer.…”

AbstractAlthough the first lasers invented operated in the visible, the first on-chip devices were optimized for near-infrared (IR) performance driven by demand in telecommunications. However, as the applications of integrated photonics has broadened, the wavelength demand has as well, and we are now returning to the visible (Vis) and pushing into the ultraviolet (UV). This shift has required innovations in device design and in materials as well as leveraging nonlinear behavior to reach these wavelengths. This review discusses the key nonlinear phenomena that can be used as well as presents several emerging material systems and devices that have reached the UV–Vis wavelength range.

“…Moreover, higherperformance DCs can reduce the number of the cascaded DCs required and achieve more compact size. A smaller footprint design and improvement of the tolerance to fabrication inaccuracies for the full metastructures with better performance and robustness can be considered by using the inverse design method [35], [36], particularly the deep learning methods demonstrated in nanophotonic design recently [37], [38].…”

A high performance polarization beam splitter (PBS) based on cascaded directional couplers (DCs) assisted by effectively anisotropic structures is proposed. The sub-wavelength grating (SWG) structures between the two coupled waveguides act as anisotropic metamaterial cladding to block/enhance light coupling for transverse electric (TE)/magnetic (TM) polarization. Cascading the DCs designed at different central wavelengths can improve the extinction ratio (ER) within the desired bandwidth or broaden the working wavelength bandwidth for TM polarization. Three design examples show the excellent performance of PBS with ER of >35 dB, 20 dB or 14 dB and loss of <0.12 dB, 0.4 dB or 0.8 dB over a bandwidth (BW) of 60 nm, 250 nm or 400 nm, which is difficult to achieve in any PBS structure reported before. The BW ER>20dB of the PBS based on the cascaded DCs increases by ∼11 times when compared with a single DC.

“…[ 30,31 ] Very recently, the inverse design method is also used to realize diamond photonics for quantum computation applications. [ 34 ] This demonstrates that inverse design method possesses wide applications for photonic devices. However, the design achieved by inverse design algorithm typically exhibits a continuous topography, which brings challenges for sample fabrication.…”

computing. This requires on-chip integrated photonic devices to have the performances of small volume, low power consumption, and easy integration with other nanophotonic devices. [3,4] As an essential component of on-chip integrated photonic devices, polarization router can separate and steer light with different polarizations of transverse electric (TE) and transverse magnetic (TM) modes into different output ports, so as to realize polarization division multiplex of channels. In the past few years, polarization routers are generally realized based on gratings, [5][6][7][8] optical waveguides, [9][10][11][12] photonic crystals, [13][14][15][16] plasmonic structures, [17][18][19][20] metamaterials [21][22][23] or some other structures. [24][25][26][27] Polarization routers based on gratings or waveguides usually possess simple configurations and high extinction ratio, but the large size restricts the practical applications for onchip dense integration. [5,[7][8][9][10] The routers based on photonic crystals possess high transmittance, but the bandwidth is narrow and the crosstalk is relatively large. [13,16] The plasmonic polarization routers are broadband and have smaller size, but usually possess large loss. [17,18] Polarization routers based on metamaterials have high efficiency, but the fabrication process is complicated and the size is relatively large. [21,23] Large size and low-efficiency excitation of traditional design cause the polarization routers to be difficult to meet the requirements of high-density on-chip integration. Therefore, it is a great challenge Nanophotonic polarization routers, which can separate and steer light with different polarizations of transverse electric and transverse magnetic modes into different output ports, are an essential component of on-chip integrated photonic circuits. By developing an intelligent algorithm that combines the genetic algorithm and the finite element method, various polarization routers possessing different operation bands, different structures, and different materials, which can be easily fabricated and integrated, are successfully designed. On-chip ultrasmall silicon-based polarization routers are experimentally demonstrated in the near-infrared range. The footprint is only 970 nm × 1240 nm, which is the smallest demonstrated. The measured normalized transmission is up to 85% in the near infrared range. Additionally, a broadband highly efficient photon coupler is also achieved based on disordered-grating configurations designed by the intelligent algorithm. This breaks the restrictions of traditional structures, provides a universal platform for the realization of nanophotonic polarization routers, and paves a way for the design and high-density on-chip integration of nanophotonic devices.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adom.201902018.With the development of big data age, the requirements for large information capacity is becoming higher and higher.
