Single digit nanofabrication for photonics at nanoscale (Conference Presentation)

Read Abstract +

We use the term “single-digit nanofabrication” (SDN) to describe the structuring and characterization of materials whose key features are defined and resolved on a scale of 10 nm or less. Achieving single-digit nano resolution in synthesis and fabrication is a central challenge for the development of next-generation functional nanoscale and mesoscale materials Single digit nanostructured materials have special properties with regard to the control and flow of energy. Energy can take, for example, electronic, magnetic, thermal or photonic forms. We will focus on how material components can be structured with high accuracy and precision in classical lithographic processes 2D and how we can achieve new or improved properties in 3D fabrication. One of the field that requires such precision, resolution and control of materials is nanophotonics. Nanophotonics covers light interactions with dielectric materials and plasmonic effects in metallic structures. In addition, we have emerging efforts in exciton transport in organized nanomaterials. PLASMONIC LIMITS Gap Plasmonic antennas are of great interest due to their ability to concentrate light into small volumes. Smaller the volume higher is the enhancement until the gap is so closed that other effect start to became more important. Theoretical studies, considering quantum mechanical effects, have predicted the optimal spatial gap between adjacent nanoparticles to be in the subnanometer regime in order to achieve the strongest possible field enhancement. We developed a technology [1] to fabricate gap plasmonic structures with subnanometer resolution, high reliability, and high throughput using collapsible nanofingers. The systematic investigation of the effects of gap size are consistent with previous findings as well as with a straightforward theoretical model that is presented here. LARGE AREA METASURFACES Metasurfaces have facilitated the replacement of conventional optical elements with ultrathin and planar photonic structures. Previous designs of metasurfaces were limited to small deflection angles and small ranges of the angle of incidence. We have created two types of Si-based metasurfaces, [2] working both in transmission and reflection modes, to steer visible light to a large deflection angle. These structures exhibit high diffraction efficiencies over a broad range of angles of incidence. We have demonstrated metasurfaces based on conventional thin film silicon processes that are suitable for the largescale fabrication of high-performance devices. EXCITONIC PROPERTIES OF DIRECTED ASSEMBLY PEROVSKITE NANOCRYSTALS Colloidal nanomaterials display a broad range of unique chemical and physical properties that make them prime candidates as nanoscale building blocks for the development of future technologies. Towards this goal, one of the main challenges resides in developing methods to manipulate these materials with a level of precision comparable with their small size. We studied the effects of topography and surface chemistry on the assembly behavior of perovskite nanocrystals PNC [3] with outstanding optical properties and great potential for applications in optoelectronics and photonics. Arranging PNCs in 1D-like features allows careful studies of the collective mechanisms of exciton diffusion and recombination in PNCs assemblies, which in turn determine the optoelectronic behavior of the system and offer fundamental guidance in engineering new optoelectronic devices made of PNCs.

The development of active photonic devices with quantum dots (QDs) as active media in the visible wavelength range promises a large improvement in a wide variety of areas from biochemical sensing to quantum computing. Novel active photonic devices including nanolasers and light emitting diodes have been demonstrated over the last years, but are primarily limited to research laboratories owing to the expensive and complex fabrication of nanoscale features with high fidelity and precision. In particular, active photonic devices which operate in the visible region impose additional challenges as the dimensions of the features are smaller or around λ/4n (λ, wavelength, n, the refractive index). At these length scales, standard nanofabrication methods such as photolithography, e-beam lithography, and molecular beam epitaxy are either prohibitively expensive, very slow or not compatible with optically active materials. Some processes require dry etching steps with plasma exposure or operating at elevated temperature, which can easily be detrimental to preserving the optical properties of active materials. Solving these issues will be the key to developing a new path towards a high throughput and large scale manufacturing of active nanophotonic devices. Here we report a dramatically simplified method to fabricate passive and active photonic devices in the visible region by direct nanoimprinting of high-refractive index materials integrated with colloidal quantum dots, demonstrated on active one (1-D) and two (2-D) dimensional photonic crystals. The direct patterning of functional materials, while preserving the properties of the active materials, represents a robust and practical solution to fabricate active photonic devices. It is a powerful strategy as it enables to fabricate photonic devices in a single step processing with the ability to tailor specific properties (e.g. emission wavelength) of a device starting at the molecular level. Active media colloidal CdSe/CdS quantum dots (QDs) QDs were applied in two different ways: embedded inside a printable high-refractive index matrix to form an active printable hybrid nanocomposite, and used as a uniform coating on top of printed photonic devices. As a proof of demonstration for printed active photonic devices, two-dimensional (2-D) photonic crystals as well as 1D and 2D photonic nano-cavities were successfully fabricated following a simple reverse-nanoimprint process. We observed enhanced photoluminescence from the 2D photonic crystal and the 1D nano-cavities. The process presented in this study is fully compatible with large-scale manufacturing where the patterning areas are only limited by the size of the corresponding mold. This work shows that the integration of active media and functional materials is a promising approach to the realization of integrated photonics for visible light using high throughput technologies. We believe that this work represents a powerful and cost-effective route for the development of numerous nanophotonic structures and devices that will lead to the emergence of new applications.
